If you are going to go the route of a drop away, I highly suggest a limb driven one. There are several on the market; pick your poison. If I were picking one today, it would be the Hamskea VersaRest. G5's CMAX looks neat too but like I say...me personally, if I were buying it would be the Hamskea.
If you go with a cable driven one, make sure to ditch the football clamp and actually put it through the downward traveling cable and serve it in. Most everybody that I know that has had a drop away rest "fail"...had it happen with the plastic clamps; mostly when it will let the cable slip through it. This will cause the launcher to not fully raise...and or to not drop if it does raise. Pending on which one it did. Either way, I guarantee you will not like the result of your shot. QAD rests are notorious for locking in the upright position and not dropping. Especially the HDX rests. These are the only rests that I personally know about that have actually malfunctioned internally and had nothing to do with the clamp. You can chocolate chip cookie the launcher up before you shoot on these particular models, and evidently something inside of them must be made very weak and after a while, is prone to breaking or just locking. I know several personally that have had this happen with them. And I know several that have cycled a couple/few thousand shots through there and never had any issue with the rest, other than going to different material for the activation cord.
