That's great advice. I definitely agree with that.You can get your HPA tank refilled at any SCUBA or Paintball store. Some stores can only fill up to 3000 PSI, but most paintball stroes near me have the equipment to ramp it up to over 4500 PSI.
Either one of those guns is good for woodsball.
Tippmann's also require very high pressure's to operate, so HPA really limits your shots98's can use both so thats kinda nice. but HPA is a lot more consistent but CO2 tanks are alot cheaper. hm....
