Hi Charlest, I have had decent luck throwing a Flipside Panic, a polished pearl reactive ball, standing on 17 and throwing to 5. This ball will strike here and playing this line it seems to go around carrydown, and make a backend snap to pocket. At this place to right of 5 (1st arrow) is out of bounds so there isn't much margin of error. I didn't try deep inside but my partner with a Crossfire was standing on about 20 and playing b/t 2nd and 3rd arrow. He usually throws a lot of strikes, very high rev, medium speed. But he had horrible ball reaction, worst splits I have ever seen. He bowled 146, 124, 146. I bowled 167, 134 (first 5 frames open with Action then switched to Panic) then 167. The week before he averaged about 200 on good lanes, and I beat him on good lane conditions. They don't strip the lanes at all for whole weekend sometimes for this Sunday night league. To me, this is the toughest place to bowl at times. But my buddy works second shift so Sunday night is only time we can bowl together in league.

ps if I try playing deep inside line I usually throw through breakpoint. Too much speed and not enough hand.
