well for you guys with ripcords, qad , etc drop aways, it appears that these rests project rearward from the riser into the "brace height "/ cable slide area . Do you still have room between the launcher prongs and nock point for 5" fletching when it is in the upright and ready to shoot position ? there is 7.2" of braceheight available.
It wouldnt be very good to have feathers rubbing out of the launcher prongs upon draw from the ready to shoot (upright) position. The revolution rest apparently wont work with them either, due to the rear part of the containment arm holding the arrow in the flectched portion of the arrow.
if you got a tape measure maybe a simple measurement from the string to the upright prongs, may help me detemine it.
