I just got a brand new smart parts ion and i dont really know what to get for it or what is the best for my gun. I'm getting a Halo-B Hopper w/rip drive, a DYE mask, and a 4+1 Harness but i also need to replace my feed neck because i heard that was one thing that needs to be replaced but i dont know what would be the best for replacing the stock one. I also dont know what kind of tank to get and at what PSI and etc. it should be for playing speedball. One of my buddies got an $11 commpressed air tank from walmart and said it was good but i want the best for my gun (in the price range of about 20-90 bucks) so if anyone has some advice on these things or maybe some more upgrades i should get - i would greatly appreciate it-thanx- JMAN
