Any general advice on playing this pattern? I was thinking a symmetrical solid to start with (on the aggressive side, maybe 2000 grit). I've never bowled on this pattern, if you have let me know please.
I had good results using a ball just like you described: an Elite Espionage, left at the stock 2000 grit but with a very weak pin (I'm rev dominant) and a largish VAL angle (5.5" x 60 degrees). Played a small swing with a breakpoint similar to that described by makpa, around 8 -10 board. This was on AMF HPL synthetics; other lane surfaces may play differently. It seemed like a medium to medium-heavy oil pattern with a 4:1 ratio so there is n't as much pull or swing area as a THS (11:1 ratio).
Transition, unless you had a good amount of ball speed to enable you to stay in the track area, was harsh. I could just move deeper. I got another version of the same ball, intending to drill it with a shorter pin-PAP and a smaller VAL angle to add length and backend, but I was injured and had to sit out the season before I could try it.
