Go with some sort of a spyder or parannah(sp?). they are both basicly the same gun and have many variations. the best type of mask in my opinion would be some sort of a vforce one. i havnt gotten mine to fog up yet(scince christmass and i play every week). i personally like the 20 oz tanks there just comfortable to me. try different tank sizes to find which one you like and likewise with the gun but as i said previously i would recomend a spyder or parannah.
