Ball spec's 15.2 3" pin 3 1/4" top
My profile: speed 14-16mph, power stroker rt hand.

Lane surface, wood, overlays and synthetic.

Drilling: 4 x 4 box finish

The Pearl Clutch not just a pearl version of the solid.  Seems to read the lane even better than the solid and has quite the backend!  New color scheme from AMF looks cool, purple and silver swirl.  Drilled this one aggressive 4 by 4 2" pin buffer.  Some midlane and hard off the dry.  Nice ball for medium's.  Has quite a strong move off dry but can hold the line with speed.  Just an awesome inside line ball for my style.  Lots of room and good carry.  Didn't play with the surface yet.  I'm sure you could use in on some medium to heavy with 2000 abralon.  This is an excellent Bang for the Buck ball!!

Right handed, 16 mph and 300 to 325 rpms.  High track, 5 3/8 over and 3/8 up.

I've thrown the ball primarily at a house with older, poor shape wood lanes, but have also bowling in a house with Brunswick Pro Anvil lanes.

I purchased the ball from Teenek, I emailed my spec sheet and my idea for the layout.  After a brief discussion, he was off to drill the ball.  A couple days later, it showed up in the mail .  Great job with the proshop services, I highly recommend!  The ball was drilled with the pin above/between the fingers and the MB just below/right of the thumb.  Basically a 5.5" pin to PAP and 5" MB to PAP.  

I initially threw this ball with the box surface on a freshly oiled house shot, wood lanes.  The ball had a lot of mid-lane and a strong/smooth backend.  It would have been an excellent reaction for a house shot league ball.  I was able to cross the arrow at 15, send the ball out to 5 at the break point and have the ball finish, without any issues.  As the lanes dried, I was able to make parallel moves inside (target and breakpoint) and still find the pocket.  The carry was actually better than I had expected.  Lots of action down the lane.

Although this was a great reaction, it wasn't exactly what I was looking for out of the ball.  I really wanted something with less mid-lane and more down the lane reaction.  Something that I could count on to get length on a broken down shot.  I hit the ball with a 2000 grit Abralon pad, and followed with a 4000 grit abralon pad.  I then finished with a light polish, using Elite performance polish (had a little left in my bag).

Back to the same house with the ball and again had nearly a fresh shot (plenty of oil).  This time, the Clutch Pearl was about 5 boards weaker overall with less mid-lane reaction, SUCCESS!  I was able to line up and play the track area, shooting 12 at the arrows, out to around 8 at the break point.  Really solid pin action with the ball.  

I threw a couple more games with my other equipment and had started to break down the track area.  I went back to the Clutch Pearl and was able to bump inside, playing 15 out to 10.  Good length, good backend reaction.

Overall, this seems to be a pretty flexible cover.  With box surface, it would handle most any house shot.  With some surface adjustments, this ball could cover anywhere from medium lights, all the way up to a decent volume of oil.  Very good ball for the mid-price point.  Nice looking color scheme too.. purple/silver swirl.  


After an 18 mo. hiatus, I''m back...

I received my 15lb Clutch Pearl and used a dual angle layout of 60deg x 3-1/4" x 60deg, which placed the pin right and even with my ring finger. No weight hole was needed cause it had lower top weight and cg was shifted slightly left from pin and mb. I loved how smooth this ball rolled thru the heads and strong arc at the break point was very predictable and easy to read. I used this on our house shot and had a great look and this will fit below my new Clutch I have to drill and the Mega Recovery that I really like. I've drilled several AMF and 900 Global in the last week and can't believe I haven't tried them before! Thanks to Eric Thomas with the layout help! Bruce

 After putting this ball on the shelf for most of last season (as the lane conditions just didn't allow me to throw it....), I moved across the country and actually found a house with a little bit of oil.  Since I had liked the reaction out of this ball previously, I decided to give it a shot.  House has Brunswick synthetic and puts out a medium oil shot... A little longer pattern.. maybe 40ft or so.  There are some backed, not real snappy.  
Threw the clutch pearl with the old finish... 4k and polish the first week.  I had a good look playing up the boards, but noticed that the ball was fairly sensitive to the transitions...initially I had to move in, but then had to move back right as the oil carried down.  At some times it was fairly sensitive... Ended up having a great night shooting spares and ended up shooting 700.  The following week, there seemed to be a little more oil and less backed, combined with me throwing the ball poorly, and.. well, struggled a bit.  

I then decided to play with the surface as I knew the ball has a strong cover.  I hit the surface with a 500 grit abralon and followed with polish to give a shine.  Wow!  Did that change the ball reaction.  Completely seemed to removed any of the "condition sensitivity" I was experiencing previous weeks.  Strong mid-lane and a controllable backend.  Moved a few boards inside over the course of the night in order to stay flush...  Finished with a 740 set having a very poor spare shooting night (four opens).

For the price of this ball, it is a very solid performer.  If you happen to find one on close out and am looking for a strong reacting pearl, it it a shot.

Length: 39'
Volume: Light

Type (THS, Sport Pattern etc): THS on synthetic lanes

Righthanded, 14-16 mph speed, tweener, high track, 184 league average. Ball is drilled strong with the pin over the ring finger.

Likes: Our house went to a lighter oil last year and I've been trying to find a ball to match up with conditions since that time.  This is the ball!  It makes a nice move off the break point, it handles carrydown well, and is consistent.  Not overly speed sensitive.

Dislikes:  None yet.
