finally went to a launch moitor and found out my avg launch angle is 23-26* and my avg ball speed was in the mid 150's spin rate 3300rpm. the ball went about 160-170 with a 8* stiff shaft 45". then i hit the ball at 16* and 150's and surpisingling the spin rate was lower at 2300's. but they both went about the same distance. so i think i have a normal swing, and a swing for when the wind with me. so i am probly wrong, but i think anything between 14 and 26* with 2100-3700 rpms (if your SS is 150ish) i think the launch angle and rpms isn't really too important.
