I am thinking about ourchasing the Tippmann A-5 with R/T and I was wonderng if it was really worth it. Right now I have a Spyder Shutter with a SP Teardrop...I am thinking about getting a Boomstick for the A-5 if I get it. With the R/T I know it can shoot fast but is that per every trigger pull or does it shoot out more than one ball per pull. I nkow that might make it auto but I have heard people say it does that. Also I heard it burns alot of CO2?? How many balls per 20 oz. would you get?? I just needs some specs on the gun to see if its really worth my time cuz I wanna start playing it tourneys...
