I used to marshall at an indoor site a long time ago - when pump guns ruled the world and semi's cost the GNP of a small third world country.
I've been playing on and off (rec ball) since then & would really technically classify myself as a newbie - compared to alot of the tourney players etc that hang around on this board.
Most of the stuff I have recommended is based on my own experience of changing from my jurassic Phantom, to something real easy to look after and in my price range! Just trying to save you some time by telling you what I've found out.
In all honesty most of the stuff I know has come from these boards and by asking in shops - the guys in Warped Sports (Wolverhampton) and Phoenix Paintball (Cannock) have been great for their techy help and info when I go in.
You work at a site in Leicester? Is it Rebel paintball (or has it gone)? Not played there in a couple of years - in fact that's where my trusty Phantom died!
Email me at the address in my profile - I'd be interested in testing out my new Inferno upgrades - need CO2 and obviously can't refill it at home
I don't play too often, but would like to get in some more games.
