I've never shot a III or a MOAB, but my Thunderstick Mag is a smooth and flat shooter. I test-shot the bow at the Iowa Traditional Bowhunters Society Memorial Day Rendezvous where Barefoot Tom had one for sale. I shot OVER a 3-D deer at about 20 yards the bow shot so flat. I let my friend try it out, too, with the same results--shot over the top. Another friend tested it, and all 3 of us shot over the target. None of us were expecting such performance. I couldn't pass up that kind of performance so I bought the bow. I would assume all of Jim's bows are great performers.
