Just because you want to switch to helical fletch does not mean you have to use a drop away rest.I used the MZE O effect for a little while and sold it but I've always shot a TM style rest by Golden Key with no problem.Arrows fly fine from these rest you have to just tune it.I currently shoot straight fletch with a 2 degree offset and get fixed blade Thunderheads to shoot at almost 300FPS. Just need to tinker with it in the off season.
