I agree that most of the drop away rests are well engineered and of superb quality. However, based on their design, it is my belief that they are really not needed unless you are struggling with vane contact. If vane contact is not an issue, then I believe that all of these drop away rests end up becoming nothing more than archery's version of a Rube Goldberg machine. Personally, I have never had a problem getting my helically fletched vanes to clear a Bodoodle, blade-style rest, nor has it ever been an issue in getting the arrow to stay on the rest throughout the entire drawing sequence. To my knowledge, nobody is (nor should they be) running over an obstacle course while trying to draw their bow!
It is generally accepted that the rest should stay up for as long as possible to provide proper guidance for the arrow and should only drop to allow for the fletching to clear the rest. There are also other considerations such as the rest's ability to withstand the loads imparted onto it upon release of the arrow. I'm not sure where the jury is on the drop away's ability to neutralize hand torque, but I certainly do not buy into it. I am shooting my 28" arrow at a relatively slow 270 FPS. On a drop away that stays up for approximately 70% of my arrow's length, my arrow would be unsupported and therefore (supposedly) unaffected by any external hand torquing loads for a grand total of 0.0026 seconds! I highly doubt that I can react to, nor affect anything at all during such an incredibly short period of time.
So, in conclusion, my Bodoodle blade-style rest does everything for me. It supports the arrow 100% of the way, it absorbs any instantaneous loads created by the buckling arrow upon release and it is incredibly simple and extremely reliable. As I understand it, most professional shooters are using blade rests for forgiveness and accuracy. These guys and gals are competing for cash and they generally know what they are doing. If they could extract some additional accuracy from drop away rests, they would surely be switching to them in droves!
In closing, I am in no way dissing anyone for their personal choices in arrow rests or any other equipment for that matter. This is my personal opinion based on my needs, backed up by my observations and many years of shooting experience.
