Just got my Freeflow back from Professional Paintball, Monday, they installed the 2k2 Racegun grip, Free Flow Ram by SMC , valve, Tungsten Hammer kit and new style beaver tail. Also the e-block and Palmer Micro Rock reg. I Had a little time today to mess around with the settings and it's up to 15.1bps with no problems and I still haven't gotten close to it's limit yet.
All I can say is Pro Paint did an excellent job and very fast turn-around.
Heres a pic of some sample- MAG Racers (not fully assembled yet) in centerfeed version. One of the racers are in Orange and the other in Black/bronze fade. Both have the compact e-frontblock from Racegun products.
