I have added about ten yards to my effective range with the DAS. It is a magic bow. I have been shooting for over half a century and have shot and owned lots of bows. I can tell you this, if you do not mess it up, that is, play with the tillering and try to do "things" to it it can be very much just another bow. However, if you have it tuned correctly, tillered properly you will have a shooting experience that will surprise you. In addition, various qualities of ILF limbs can be put on the bow affecting the shooting characteristics. My first DAS had Hoyt G3 limbs that were dogs compared to the Winex limbs that are on my bow and my wife's. My wife shoots 45# @ 26" and her bow shoots right up there with any number of high end bows that I have that are 60+ at 28". If you are a person who is not good with tuning and doesn't understand tillering then the bow can be a headache. I had a fellow bring a Dalaa over to "fix". He had trouble setting it up. When I got it it had me stumped for a while until we set it up for even tiller. The bow came to life at that point. I think they are amazing bows and, in response to your original question I have found that I can get about 10 more yards added to my effective range. Part of it is the cast, part of it is the stability, and part of it is the limbs you choose to put on it. I am not saying that anyone here who has posted that the bow is not "magical" isn't capable of tuning...but my experience has been that those that have trouble getting top performance with them really had the same trouble with that issue to begin with and I have found myself educating people about such things as tiller, nocking points, brace height, bare shafting, etc.
