Well, in all reality, I believe these are sort of basics for many of us longer term users on this site.
I was not in my comfort zone which used to be called if a tournament it was FTL. Now my comfort zone is a 35 foot shot!
Also there was a hang spot outside 8 on this shot right next to the breakpoint....
So the bowler is trapped hitting about 9 -10 at 43 feet.......Sonic X 18 diff and Sonic Boom .35 diff balls are leaving buckets and washouts in practice off of the 10 spot. Drilled moderately strong they produce about 2 or 3 inches of of flare.
A switch to .50 diff balls now produces with similar to slightly weaker drillings about 4 to 5 inches of flare for this bowler. All of a sudden we are flush and slamming them despite the holes in the ball.(malarky above). A quicker response coverstock on both the AMF Shred it and (mass bias strong and fast response coverstock)The Brunswick Ulti Max(playable more like 14 to 10 for me). Also combined with extra flare didn't hurt either.
Despite the holes in the ball, these .50 diff balls flared more and got flush easier than .18 diff balls. Surprise!
Twohand, I have the Freeze listed as a .047 diff ball much like my Spell.
http://columbia300.com/products/detail_balls/freeze_blue_green/My partner used this as he struggles going inside with his Virtual Gravity which would have been sweet. He did well but even the slightest amount of belly with the Freeze orignal left him with a 5 or 7 count. (My Track Spell with particle made it much easier!).
We had fun, we learned, we are AGAIN ready for longer oil, despite the holes in our balls! Probably will continue with at least 3!
