I know there is probably hundreds of threads out there saying, "what should I do to my gun to make it less of a piece", but i think those work so I'm gonna do it

so the gun I have is a spyder tl-x i've had for three or four years and i just recently got back into paintball. its stock right now, but i plan to change that. I don't know much about upgrades or what I should do to it, but I'm thinking a barrel and a hopper are good places to start.
