I just baught a brand new smart parts ion and i'm looking to upgrade as much as i can to make it a perfect speed ball gun. I've already baughten a Halo-B Hopper w/Rip Drive but thats it! I dont know what kind of tank is the best for my gun and for speed ball, I dont know what kind of barrel i should upgrade to (I play pointman and mid-player)i need to replace my feedneck but i dont know what kind i should get. I know there is a lot of other things i should upgrade but i'm only focusing on a tank,barrel, feedneck and anything else that would go along with these parts for the time being due to money. The biggest thing i'm conserned about would be the tank and possibly some king of on/off valve so i dont lose pressure when disconnection. So if anyone has any advise on what parts to buy i could really use the help ---- THANX - JMAN
