Alpha I would have to disagree with you on the whole "dont upgrade your gun" thing. I bought a Tippmann A5 and have seriously upped it. Sure, It might not be quite a Dm5 yet, but I think i can get about 13 bps with a double trigger and a Rufus Dawg bolt. I mean, for things like woodsball and mounds, thats all you need. Heck, I can play speedball pretty well with this thing. (I'd compare my gun to an Ion that is just a bit low on gas. It shoots hard, but just not as fast as a fully gassed Ion would)
PS. I'm trying to keep constructive criticism, lol.
**EDIT**I also have a Smart Parts All-American. But maybe this whole "upgrading low-end guns" makes more sense to me than to you since I plan to keep my gun indefintely as a project gun, yet most people only keep a Tippmann until they have enough money for like an Impulse.
