I think you' ll find a LOT of top shooters useing drop away rests on one cam bows. And they won' t use it if it doesn' t mean top performance to them.
EVERY bow I have put a drop away on shot well, and was easier to tune than shoot through rests. This includes several different 1 cam bows, and a few 2 cam bow as well.
Do a search on the Muzzy Zero effect, and see how many happy campers with 1 cam bows you find (LOTS!!!)
I personally shoot an ARC Systeme drop away, but I REALLY like the Muzzy too (In fact, I just put one on a bow for a friend...Mathews Ultra-Max).
I can get Muzzy' s to group with field points to 40 yards (haven' t tried farther) with nothing more than 3" " Kurly Vanes" with my Stealth Force.
Don' t fret nock travel...drop aways simply WORK when set up right.
