Continuing the highly successful Mixed Breed line, the Mixed Breed Pearl  is the perfect choice when the lanes start to break down, and the solid  is just too much ball.  Using the same core as it’s predecessor, the  pearl version will clear the heads and mids easily, while generating  more backends and the same continuation through the pocket as the solid.
 The Mixed Breed line uses a strong asymmetric core design, boasting an  intermediate differential of .015″ and a total differential of .052″.  This allows the ball to not only get into an early roll, but provide a  strong breakpoint with tremendous continuation.

Weight: 15.15lbs


Top Weight: 2.25 oz

Pin: 4-1/4


Length: 40ft

Volume: Medium

Type (THS, Sport Pattern etc):THS


Likes: Clean through the front and continuous on the backend

Dislikes: Not good on heavier volumes

This ball is great for medium to dry lanes. I've tried this on a THS shot during a tournament on second shift team squad where right of 15 was fried, an oil strip 15 to 15 with blended backends. All my other pearls and solids were too aggressive so i deceided to try the MB Pearl which i drilled the night before without throwing any games. The MB Pearl was clean through the front, reved up in the midlane due to the low P3 weight hole and had a nice continuous backend. I started playing 16 to 12 and as time went on i ended up playing 20 to 12. The type of shot is like playing a fall back shot. I can feed it from wet to dry or stay in the oil and the bal would still carry. The key was chasing the oil in and keeping up with the transition since everyone on my team and the opposite team crossing with us was playing the same part of the lane. 


Finding the right layout was a challenge because there are so many possible variations. I talked with Jason Wonders over two weeks until i understood the dynamics of the ball along with what i wanted this ball for. Since this was a Z Spin

type ball, it has to treated completely different. If anyone remembers the Hammer No Mercy, this is the way the Mixed Breed should be drilled but since the pin, cg and intermediiate mass bias was all inline i had to go with an alternate layout. To find the actual MB like the typical Y Spin assymetrical balls out there on the market, you first take the "prosect" and put the "0" at the top of the pin, then run the middle rib all the way down towards the "V" marking. Then the two opposite ribs at  the ends of the prosect is 6-3/4 inches from the "V" which is the actual mass bias. You would normally put the "V" 2 to 2-1/2 inches left thumb in the bowlers track which would then put the MB 4 inches right of thumb for righties and 4 inches left for lefties. To get a more defined reaction you would use the Mo Pinel Gradient Line concept. Placing the weight hole in the right location is critical. For me, i had to put the "V" 4 inches right of thumb so the MB would end up 2-3/4 inches left of thumb. I kept the pin above my ring which is 5 inches from my pap. To get the actual MB to be right of my thumb, i drilled a weight hole in the P3 location which is 2.5 right and 1 inch above thumb. I used a 7/8 drill bit, and pitched it away to avoid contact with my thumb. I drilled it 2-1/2 inches deep and drilled my fingers 2-3/4 deep. The ending static weights were 7/8 side and 5/8 finger. This layout changed this ball from a weaker pearl to a more stronger one.

Length: 42' and 39' 


Volume: heavy

Type (THS, Sport Pattern etc): very wet \ dry THS on old wood lanes



Likes: Having drilled the Solid a bit weaker i went extreme on the pearl (see picture below), and couldnt be happier. Warning if you do not have enough oil up front this layout may not be the greatest idea!!  The pearl glided through the heavy fronts then made a strong strong move on the back end. Carry was excellent and the ball reacted favorable to hand position changes.


Drilling:  as everyone knows these balls are Z spinners and to avoid a lengthy explaination of how to drill a Z spin ill summerize.  Put ball on determinator ... spin both sides to get the left and right Z axis... drill ball. ( you can use a prosect to get the axis points also )


In a nutshell the closer you move the left Z axis (right if your a lefty) towards your thumb hole the stronger the ball reaction will be.  You have to be careful because if you make it too strong and you do not have enough head oil it will flare way to early and hit very weak.


What i suggest is if you are using the DA method measure your drill angle off the Z mark to the pin and use drilling angles of 60 - 100.  I know that your not supposed to go over 90 but for these balls 100 even 110 will be ok. Just watch the Statics as you move the Z axis towards the thumb. 


I had to increase my val angle to 40 from 30 to keep the finger weight in check.  Had to add a very small hole 1" below the midline on the VAL to get the side weight legal. ( picture linked does not show the weight hole as it was added later)


So using the DA method of (Zmark to pin) my layout would be 60 x 4 x 40

Dislikes: none

Miscellaneous Information
The Mixed breed pearl is my go to ball when the lanes start to dry out and for short pattern.  I like the way it rolls up at the break-point, very smooth and controllable. It makes a strong move towards the pocket and hits like a truck. It is good continuation through the pins. This ball does not roll out and it keeps the pins low and leaves very few corner pins. I would recommend the Mixed Breed pearl to anyone, a good ball for any league shot, if you’re looking for control in a ball.

Length:  Drilled with the intention of going long because of my low speed.  The b pin is approx 4 1/2 inches from axes point.   Medium flare positions. 

Volume:  Medium

Type (THS, Sport Pattern etc):


Likes:  Very controllable

Dislikes:  Heavier oil conditions

The Mixed Breed Pearl is a great transition ball for use on a shorter patterns or medium lane conditions.  The ball is very smooth and controllable.  I have never bowled with equipment with such a smooth and continuous roll down the lanes.  Even with my low revs and ball speed, the ball holds its line and at the break point, beautifully arches to the pocket and through the pins.  I just love the backend reaction.  I have been able to use the ball to shoot for spares and the 10 pin with ease.  Just a very versatile ball.

Length: 37 feet

Volume: Medium

Type (THS, Sport Pattern etc): THS


Likes: Clears the fronts with ease and is a beast on the back end.

Dislikes: Solid 8's and 9's.

It’s been a while since I’ve gotten the chance to write any new reviews.  To be honest, it’s because I haven’t had to buy any new balls for the past year and a half or two years.  Those Visionary covers just last forever.  In fact, I’m still using some of the balls that I originally got from Visionary over five years ago!  But when they came out with the Mixed Breed pearl, a strong asymmetric, I just had to give one a try.

Since the Mixed Breed is a “Z spin” asymmetric, I spent a lot of time researching how to drill it.  As it turns out, I was making it a lot more complicated than it needed to be.  The simplest way to think of it is:
•   Put the pin up around the fingers somewhere for a good all-around drilling.
•   Put the “V” directly in your thumb for the tamest possible drilling.
•   As you swing the “V” away from the thumb, the ball becomes stronger and stronger until 90° off the “V” is in your thumb, which would be stronger than anyone really needs.

I started with a pretty large pin out (right at four inches) and low top weight.  I settled for putting the “V” four inches off the thumb.  The pin ended up directly in the ring finger.  I then used a “double thumb” weight hole.  By all accounts, this is a pretty strong drilling.  Not insane, maxed-out strong, but I wanted something pretty muscular that I could still use over a wider range of conditions.  I left it in box finish and headed for my first league night of the year.

I started the night playing nine at the foul line out to five at the break point.  The first game was 11 shots dead in the pocket for 204.  A solid six pin, two ringing sevens, a solid eight, and a pair of solid nines.  I finally realized that, with the ball being a strong asymmetric, I didn’t need as much axis rotation to maintain continuation on the back end.  It was just generating too much angle through the pins.  I backed off the rotation some and, after a few high shots due to the ball getting into a slightly earlier roll, finished with a nice 233.  The third game I had to begin chasing the oil to the inside.  But it seemed no matter how deep I moved (and I ended up playing 15 at the foul line out to 5 at the break point), the ball still had great continuation and hit even with the lower axis rotation.  I would really like to say that I had a 300 with the ball the first time I used it, but a solid seven in the 11th kept me to 289.

My overall impressions were that the ball would work great on anything from fairly dry to the slicker side of medium and maybe even some heavier conditions if the pattern was short enough.  It was clean through the front and early midlane, began to get started in the later midlane, and really turned for home with bad intentions.  The outstanding recovery and continuation would make it a godsend when playing deeper lines.  I was extremely impressed with how well the ball responded to the change in hand position.  It allowed me to moderate the back ends somewhat to generate the proper entry angle without worrying about losing hitting power or continuation.  I can’t wait for next week.  Outstanding job, Visionary!
