RE: Drop away rest vs. Wisker bisket???
I'm a proponent for basic simplicity in a hunting rig. The simpler it is, the less that can go wrong with it. You can't get much simpler than the biskit.
I'd definitely trash the old style biskit and update it with the new sideloader type. That sideloader design eliminated my second biggest objection to the WB. First biggest is still the 100% guaranteed fletching contact, but that's far easier to accept than the possibility of a rest malfunction during the shot of a lifetime.
Dropaways.... I MIGHT consider one for a dedicated 3D bow. No way I'd put one on a hunting bow.
