last Sunday i bowled on the usbc pattern, but was on a different lane surface. i was able to play around 10-8 for the first game, using a Sauce: 70* x 4", pin up. the x-hole is on VAL above my pap to decrease flare. surface was 500 / 4k
as long as i stayed firm it gave me a nice reaction. unfortunately we had to move pairs for the tourney and thus you see how important it is following a group who plays them correctly.
did see some guys at end of day using pearls and slow looping it. not sure what layouts were, but looked like something that picked up in midlane and rolled strong for them. skid/flip didn't have as good as carry inside.
