Never a truer word spoken.....as JTL says, try them all, then see what suits you best...
I had a play with an Impulse, and hated it, whereas a good majority of players would swear by them, the guys I play regularly with love Tippmans, and I really don't like them. One of the tippy guys just tried a cocker and was hooked, if you like the way it feels and you get on with it, then that's the marker for you..no matter what another player tells you....
