yes yes yes. i am in a tourny tommorrow and it is psp rules, you can turn on rebound and you just have to set it to shoot 15 bps go here
go to tech articales, then go to ion electronics. scroll down the page and go to were it says recharge. read it and it will explain how to set teh speed of you gun. it has a cool calculator thing on the page. you plug in your dwell on your current gun, and then you tell it what speed you want to shoot. i plugged in 13 dwell and 15 bps, and it spit out that i should set my recharge 49.33 from the bottom. i put it to fifty to be safe and then matched it with my friends DMC which has Psp ramping as a setting and they shot the exact same speed. sorry i started ranting there.
