I'm using a Pro Tuner. I really prefer a spring steel style rest over anything else out there. The Pro Tuner is the cream of the crop when it comes to spring steel type rests. If you don't want to spend the $$$ on a Pro Tuner, the actual TT Spring Steel (get the 2 hole rest model) is second in line, but doesn't offer the no tools, micro adjust options a Pro Tuner has. Also, after several years, a Pro Tuner will begin to round out on the allen screws, the track that the unit moves on for windage/elevation will start to mar from being retightened multiple times, etc. I've got both of them, and I still keep the spring steel around just in case I want to setup another bow other than whatever I'm shooting as a target bow at the time, but when I have a chance I will pick up another Pro Tuner and retire this spring steel.

To tune a Drop Zone so that it's cord isn't yanking on your cables affecting timing (happens whether you are tied to the slide or down cable), you have to time the rest so that it hits the full draw position in the last few tenths of an inch in the draw cycle. Now if you creep at all on any shot, that creep is affecting where the rest is.......full up position or slightly dropped. I don't care who you are talking about as a shooter, if you video a good shooter for 60 shots your gonna catch them creeping occasionally, and this is only magnified when you have bad footing, up/down hill shots, etc. This is why I would never consider having a drop away for any reason or purpose that is activated by the cable slide, or cables. The only drop away I'd consider to be honest would be a Limb Driver, because it's actuated by the limb rather than the cables. That's a LOT more consistent of a way to make your rest drop than messing with the cables.

Just MHO.

If everyone took video such as this of themselves for 60 shots in a row, I doubt they would ever consider another cable driven drop away again. With a cable driven drop away you can actually see the elevation of the arrow shaft change when you creep from this view.
