It's not that there aren't a lot of nice rests out there. The problem is with the '05 Bowtech Defender itself. The riser is very thick and the cutout is very large. Both of these things make it hard to find a rest that will have enough horizontal adjustment to work. The rests that I know will not work without a lot of engineering include the Muzzy Zero Effect, any NAP drop away, TR Drop Zone and TT. I know there are others out there but I tried the QAD and am very happy with it.
