My TRX is a single cam.
fletched and bare shafts hit in the same area (3" circle)
bare shaft nocks are at the top of the circle while points are at the bottom
Overall seem to group very well with fletch shafts almost to good (probability of spliting arrows very high the more I shoot).
My beman carbons have outserted nocks which I thought to be a clearance problem in previous setups which is why I went with a drop away arrow rest this time around.
