I agree on both accounts with Greg, the speed gain of switching would probablybein the 3 fps range (I did it once and picked up 4 fps, granted, that'snot enough to motivate you to switch as you won't even notice thistinychange in speed). The main reason I switched is becasuethe Whisker Biscuit cuts down your vision when you're at full draw, it blocks a great deal of the sight window and that's not good for hunting.I heard the Whisker Biscuit is the #1 rest in America so it can't bebad but in my opinion, you can't beat the Zero Effect. It's solid, easy to adjust,your arrow can't fall off during even a super quick and jerkydraw (buck fever draw;-), the plastic arm won't ever change in length like string attachments on somedrop away rests can doand it'sas reliable as anything out there. The only thing I do to mine is clip about an inch off the thin end of the arrow rest so it does not catchon the brush while walking through the woods.
