I have an AR34 and love it. I went to a string loop because I have a sursapeep (one without the rubber tube) and this makes it turn the correct way everytime. I did not have my draw changed and only noticed that the breaking point of the pull back is a little closer to full draw. My dealer told me I could have the draw changed to 28.5 from 29 on my AR if I wanted. I like the speed for 3-d so I am leaving it at 29. I am not sure how much speed I would loose. The AR is priced in the same group that other good bows are price at. You can get more speed out of the AR70 (the longer one) than the shorter ones. The AR is an nice bow and I am not disapointed with it at all.
