RE: What rest????
If you are looking at drop-aways then I'd have to tell you I had nine of them on my bow last year. The absolute best out right now is the GKF Infiniti. That's what's on my 3D bow. My hunting bow carries a Trapdoor for reasons that I won't get into. One reason a lot of the droppers got thrown out was I could not stand those that had the cord attached near the arrow pass. Darn fletching was sometimes contacting the cord. Not enough to affect arrow flight, but enough to affect my mind. I mean, the whole dea of a dropper is "No Contact".
Ya know what else I see a lot of? I was just at an ASA shoot this past weekend and most of the Pro's are sporting the tried and true launcher style rests. I guess they figure if it doesn't move then nothing can move (reliability).
