You need to go farther back in the Tippmann line of markers to find the siphon'ed CO2 ones. Pro/Carbines have the CVX valve and don't mind HPA at all. I use a 13/3000 on mine and it's never had a problem.
Woops, B-17 got to it before I did. IIRC the Pro/Lites and Pro/Ams had the older style valves while the Pro/Carbine was the first to use the CVX.
