hey guys. my current arsenal consists of the agent, ambush and scorchin' inferno. i need replacements for the ambush and scorchin' but i can't really decide. can u guys help?

i'm a right bowler with average revs, high track and ball speed of about 18 mph. i don't really know how to see the angle of rotation, all i know is my roll is not too forward or too extreme. i like to play the inside line(not too deep) and have my breakpoint at around the 8 board.

any help is appreciated. thanks a lot!
