Title: Pin length question
Post by: lefty50 on April 10, 2005, 11:30:10 AM

Is this a true statement?

"High axis rotation bowlers may have trouble with longer pin lengths, since longer pin lengths have a comparative tendency to slide past the break point."

Side question - What's the basic advanatge of a longer pin length? Versatility in layout, ability to generate more backend angle,.....?

Thanks in advance.

Thanks, that answers part 2, but I'm not certain it definitively address part 1. I'm afraid the answer I'm going to get is "It depends", but let's try anyway. Layout aside, does pin length itself have an affect on break point for certain bowling styles?

Yes,

Pin up drillings give more length.
Bowlers with high axis rotation(over 45 degrees) have strong side roll.  These bowlers tend to get a lot of length to their breakpoint due to their release.

As a result a pin up drilling on a pin out ball with strong side roll and good midlane oil gives too much length.  Also these bowlers often have dramatic backends from their release, now even more dramatic coupled with a pin up drilling.

Therefore often these bowlers are often trying to control( or move the breakpoint closer to them).  Surface, pins no higher than pap to ring finger line, and cgs out(some companies disagree with this last one) lead to a earlier more even breakpoint!
