I converted my old vest into a MAV. One thing that you need to watch is the lack of back space for whatever reason. This is easily remedied by a nice backpack. Drop Leg holsters seem to pull the actual rig down, that is easily remedied by converting/purchasing a belt holster. I actually am going to end up using my leg straps as my BDU belt and have the holster sit on that. I haven't used the holster in this configuration during a game yet, but during the test fitting it worked really well.
IMO the comfort is superb, much better than before I converted the vest. This really just eliminates all the extra unused space on the back/sides. I'll see if I can get some pics up.
