if the pro shop definitely know what they are doing they should measure ur pap and drill according to that, many people here dont do that.
as u said, u r a stroker, that means u cant expect the ball to turn a lot because u dont have the revs. If you want the ball to snap hard then the scorchin may not be the best choice. ur best bet as the pro shop said, is to slow down, rev it up and then speed up but slowly, u cant just increase speed and revs and expect it to hook

When a house bowler misses the mark, misses the break point and strike, for many ppl its called a wallshot. When a pro does that its call adjustment
When a house bowler gets his finger stuck in the ball and fall on the lanes, for many ppl its called lame bowler. When a pro does that its called the Machuga flop! ha i like this one.
