So I suppose I should begin this post by letting you all know I have been on about a 6 year hiatus from paintball. Some of the old members here on SO may still remember me; if they're still around... Marriage, graduating college, a real job, two kids later and here I am. So that brings me to my question; I realize there have been a lot of changes and innovations since I left the game, but what is the most efficient valve type/marker out there? Where does the mag rank in relation to most?
