RE: switching?
The chief benefit of the drop-away design is to reduce fletching contact with the rest...especially if the bow is not tuned properly or if you use an agressive helical fletch on your arrows. If neither is the case then many of the current drop-away design won' t give you any signficant advantage. However, some drop-aways, like the Muzzy ZE, also have a large " rest/launcher arm" area that also helps to keep your arrow where it needs to be prior to and during the shot.
