lol yeah 1200.....on a vibe is a big maybe I guess.
Im not really sure about the numbers, but I know you can get 500-700 off a 48/3k on an ion.....which is plenty if your sticking to woodsball. or light speedball.
1200 on a 68/45 sounds about right for an ion, but I might be a little high....I just dont remember.
What website can i find this 48/3k tank at?
