well in order to answer to jason and be faster and overall better then him i just got these. going on in 2 weeks. you guys will say all the usual SN stuff like "do the PI swap" or "you wont gain anything since your NPI" and "PIITB". well my goal is to run 12s with a NPI before i go PI and i like being the underdog. i think these will help my N2O alot. i should have 12s now. oh and 12s are hard to get over here in PHX. dam this hot weather.
