I just watched Masters of the Barebow (for about the 4th time this week) and watched the creator of the DAS bows explain the bow and demonstrate shooting it. I have to admit, it shoots darn good. It wouldn't be for me. I like simple. I can confuse myself enough deciding on brace height, nock point, arrow length, etc. that goes with plain old recurves and longbows. I'd have to have my engineering major son come home to help me adjust my bow!
If they work for you and you can figure out all the adjustments, have fun with it. That is what the sport is all about.
