Thinking of drilling an Equation 5 1/2 x 5 1/2, pin 3 1/2 above GC.  This should put the pin above and between the fingers, and the "mass bias" (yeah, I know it's symmetrical) a little left of my thumb.  The ball I got has a 2.5" pin.

I expect this ball to go long and have a huge backend off the dry.  It should fit under my Machine for med/med-light patterns, and be very helpful on Cheetah.  Does this all sound good?  Should I push the pin up a little more?  My PAP is 5 3/8 x 1 5/8.  I have lower revs and throw 16-17 mph, semi-roller track.  Thank you.

Okay, but I should add that I don't play Cheetah outside of 5.  I play inside, which can be anywhere from 20 over 12-14 to 30 over 12-14 depending upon how burnt the heads are.  Of course I have had problems with doing this, but I hate the "risk-reward" line, and up until now, I had not had a ball weak enough to do this with.  Now with my Equation, I felt that I could do better playing the inside track because the ball was weak enough.  But, as you have said, big backend on this pattern is generally not the best way to go.  I can see what you mean; a more "arcy" ball will not jump so quickly off the dry boards too.  Logical.  But I will want to try the Equation OOB on house and Cheetah before I go changing it, of course.  I'll have to see how the ball reacts in both cases, and then under both conditions 1000-2000.  Thanks for the advise, Carl.  I appreciate it!
