If you middle fingure is hurt, just switch to using your pink and ring finger. This has worked for me and my friend.
Not a bad way to kill off all your revs too! I have a friend with the straightest swing you'll ever see and I remember watching him throw 960/4 one night like that when everyone else struggled to get it down the lane. Back in urethane days too!
A common thread in this thread is that the Recon is stronger than expected. I've had this issue as well. My league house has the AMF issue 10-10 PHS (Pathetic House Shot) and my RX-1 is a 3 and 2 move left off my TX-1 as a result of all that friction! Not a complaint, merely an observation.
I'm a righty who is afflicted with a 450+ rev rate and my PAP is old school, 4 1/2" x 3/4 up, speed circa 17-18 mph on the dry. (I learned to bowl with polyester in the 80's and am still working on killing the shot off everywhere I go.) I drilled the ball 4 1/2" pin to PAP, 5 5/8" derived MB to PAP, pin above bridge. No x-hole. The ball just leapt off the spot! I could get it to the pocket, but if I backed off or tugged it - trouble!
So I polished the ball to get to a better break distance-wise, then put a 13/16 P2 hole drilled deep (I stopped at 3", -7/8 oz SW) to get it to arc more off the spot. Use less cover, more core dynamics. The ball still covers the same amount of boards, but the stone 9's have almost gone away! This ball does some really mean things in the pin deck. Looking forward to punching a Cruel up in a week or so.
Now I just need to get some practice in!
So I'd recommend using a medium early drilling on the Recon RX-1, to tame it's angularity if you have plenty of DIY hook. Then I think you'll love like I'm loving mine.
Hopes this helps the high rev folks out there.
