The biggest problem is that these bows require a little more arrow" support" to get through the initial down movement of the nock. When a dropaway is set up according to most of the instructions, and drops very soon after the release, the support is gone. The down travel of the nock will continue down and fletching contact is very hard to eleminate ,as well as getting a real good tune.

The simple answer is to support the arrow for a longer duration of the shot. But this is also very hard. When attaching to the down cable there is only so much pressure you can put on it, and only so much you can get the arrow to raise sooner. When attaching to the cable slide there is only so much load you can apply to it and stop the cables from mooving back on the rod.

Some bows and some rests just don' t match up that well.
