RE: whisker biscuit damages vanes
I have a shaky hunter, drop zone, biscuit, tiger tuff prong rest- all hanging on the pegboard waiting to be mounted whenever I feel the need to switch.
Right now I have the B2 mounted up and will most likely leave it on. If you do any ground blind hunting it is a benefit to have the arrow stay in place when manuvering the bow inside the blind- that arrow sitting way out in front of the bow while at rest always wants to grab the wall and bump itself off a traditional rest.
The are also the way to go for stalking also.
