RE: BISCUIT OR DROP-AWAY
Best rest for what? What do you want your rest to do for you? What kind of shooting do you intend to do? Hunting? Target? 3D?
If it's to be a rest for strictly hunting and recreational target shooting, I'd go with the bisquit because of it's simplicity. If it's to be used for serious competition, even if youalso intend to hunt with the same setup,I'd suggest the dropaway because it's capable of greater accuracy at longer distances.
