Perpetual Motion
« on: December 31, 1969, 06:00:00 PM »
Ball NPS Score: 100.00
The PERPETUAL MOTION is our first symmetrical cored ball! We've combined our new RESPONSIV pearlized cover with a HUGE symmetrical core to create a ball that is clean through the front of the lane with a continuous hook from the break point to the pins. This gives you tremendous hitting power at the pins AT A MORE AFFORDABLE PRICE!
Expands the spectrum of the ball reactions available from MORICH.
Designed for light to medium lane conditions; add surface for more oil.
Excels on most house patterns and on shorter, more competitive oil patterns.
Has a HUGE symmetrical core that gives it great versatility with different drilling techniques.
.054" total diff. for large flare, improving traction on the back half of the lane.
2.470" RG for more revs at the break point.
Weights: 13 - 16 Pounds
Available in Garnet Pearl & Gold Pearl

Great roll and versatility in Mo’s first symmetrical core ball.

The Perpetual Motion is MoRich’s first symmetrical core ball and fills the space between the Mojave and MO’s recent asymmetrics (RipR and DestroyR). The PM features a high density version of the Bruiser core most recently used in the Brunswick Monster Bruiser but first made famous in the Brunswick Technical Ventures’ Quantum line of premium balls in the 1990’s. The Quantum and Monster Bruiser are still good on the light-medium and lighter conditions of today. But by marrying an excellent core to a modern super coverstock (Level 2 Reactive), MoRich has, in essence, resurrected the Quantum ball motion for a new generation of bowlers.

My Perpetual Motion was 15 pounds, 3 ounces out of the box with 2 ounces of top weight and a 4 inch pin to center of gravity distance. It was drilled 60 degrees by 3.5 inches by 30 degrees. No weight hole was needed. This is essentially the medium reacting layout specified on Mo’s simple suggested symmetrical layouts sheet. The difference between the medium and most-hooking layout is the addition of a P2.5 gradient line balance hole. My PM rolls great without the GLBH so it remains in the medium reacting layout configuration.

I have used my PM at box surface (500 Siaair, 1000 Siaair, Rough Buff Compound) and at 2000 Abralon/4000 Abralon as well as 1000 Abralon/2000 Abralon and 500 Abralon/1000 Abralon, on low and medium volume house conditions and medium and high volume sport conditions. The PM is remarkable in its versatility in being able to get to the pocket and carry with good coverstock to conditioner matches across this wide range of conditions.

The Perpetual Motion is not a replacement for the Mojave, 300C or any of the other mild pieces available. Likewise it is not a replacement for the mania, Invasion, Mega-Friction or any of the heavy condition specialists. The PM is a ball that will cover all of the medium-light to medium-heavy conditions with proper surface preparation. Out-of-the box, the PM is ready for medium-light to medium. I’m currently using my PM at 2000/4000 Abralon with excellent results on the light-medium to medium THS I encounter on a weekly basis. At 4000, my PM gets excellent length then makes a strong move (hook, not flip) late in the midlane with excellent continuation through the pins.

• A good two-ball bag: RipR and Perpetual Motion
• A good three-ball bag: DestroyR, RipR, Perpetual Motion
• A good four-ball bag: DestroyR, RipR, Aggressive Motion and Perpetual Motion

This is a great ball for all of the Quantum aficionados out there: An update of one of the 1990’s most sought after shot shapes. The PM is also an excellent symmetric companion to an asymmetric arsenal. On days when your favorite asymmetric isn’t carrying, sometimes a move to a good rolling symmetric will be the answer (and visa versa).

Coverstock durability? 190 games into use of the PM, there is no discernable coverstock wear. The Perpetual Motion should be a good choice as a versatile, long-term tool in your bag. Way to go MoRich!

Bowler specs - low speed (14 mph), average revs, 45 degs axis tilt.
Ball specs - 16 lbs, 3.3 oz top weight.
Drilling layout - Pin/PAP x CG/PAP = 4 1/2" x 3 1/2" , balance hole on PAP, surface set to 4000 Abralon with polish.
I was looking for a ball to give me more control while playing on the White & Blue patterns; there were times when using my Dark Star ended up just too straight due to oil transition and my next ball "up" (such as the Freeze) still flipped too hard to match up properly.     While browsing across different balls, this ball core caught my eye.  It reminds me a lot of the Brunswick Quantum's mushroom core back in the 1990s.  Coupled with a cover that's not aggressive (but not mild either), I decided to give it a shot.   Whoa, the first thing it wants to do is skid (does that ring a bell ?) and rev at the same time.   Then suddenly, at midlane, it comes back in a nice smooth hook/set (it is NOT a skid/flip).   I found it to be very useful on these USBC patterns.
Then the other day, I was subbing in a league at a AMF (synthetic) house with house oil and tough back ends that hook a lot.  I opened the first game with the Perpetual Motion using a normal 3rd arrow down & in target line and rolled a 299 while I was still getting loose!  I was HUH ?  But unfortunately in the 2nd game the lanes broke down too fast and I had to change the ball again (to longer balls such as the Dark Star, mentioned above).   But I realize now that the Perpetual Motion is a very good ball for wet/dry and/or fresh back ends (due to its coverstock) and has very consistent behavior (due to its core) which is what I was looking for.    For lane breakdown in oiler houses, this ball will shine by using deep lines (3rd and 4th arrows) after the next ball "up" had lost its consistency.    
Be aware that this ball is not for heavy oil.   It will need some dry on the back end to make a read and do its thing.  It does have a weakness in carrydown which causes it to ring the 10-pin.   But other than that, I really am impressed enough with this ball to put it in my arsenal as my "go-in-between"/transition ball.

Likes:  Medium oil with some dry (but not too much) in the back end.  Dominates on inside lines (3rd, 4th, and 5th arrows target lines).   Will work well from medium to medium-light.

Dislikes:   Carrydown oil.   Doesn't like heavy oil and doesn't like dry lanes either.


"Hink"  -  Storm bowler with a few RotoGrips & Ebonites on the side - and one Hammer thrown in the kitchen sink   Plenty of competition in L'il Rhody if you know where to find it !
