I have gone to the Spot Hogg Whammy this year and imo,it is the best rest on the market by far,unless you shoot a Hoyt Vectrix,It won't work on them but it works flawlessly on all others and is a breeze to setup.

This rest gives the ultimate in arrow guidance,only falling out of the way at the very last milisecond and resets immediately for another shot.

This rest does not pull against your cables at full draw so it doesn't mess with the timing of your cams.The rest is attached to the up cable so it has slack in it when at full draw,watch the video.

And it has micro adjustments in the horizontal and vertical planes.
