ANY movement of the bow will effect the arrow flight because it's attached to the string, no matter what rest you have on it.

As for the Whisker Biscuit, the arrows fletchings are already in the Biscuit when the arrow leaves the string. We are talking aboutmilliseconds of contact time after the arrow leaves the string!!

There is no way any of you can convince me that this thing doesn't work. Is it the rest for everyone? No but don't try to tell me it doesn't work because it does and very well at that. I am not a pro shooter nor a bow tuning expert but I was able to install the rest, set it up and tune it in about 20min and was shooting both my field points and broadheads in the same groups.

The rest is as accurate as any I have ever shot. If you use the correct opening you will not experience any vane damage at all. I really think this is where most people are having their problems (the ones who actually do, not the ones who just talk about them) The rest dose make some noise however not enough to spook any deer I have ever shot with it and that includes some that were less than 5yds away. Again if your biscuit is too loud odds are it's the wrong size.

Mine have NEVER needed to be readjusted, customized, trimmed, sprayed or anything. It's never bent or gone out of adjustment. It's never had it's stringstretch or break, never needed to be lubed, never needed it's mole skin or shrinkwrap replaced. It's never had the little arrow holderstuck to the shelf come loose. It's never froze, melted or rusted. It's springs have never become weak or broke.It never needs me to hold the arrow on it no matter what position I hold the bow or where I put it.After they were installed and set up no more maintenance has been needed....ever.To be honest if it wasn't for these threads that keep popping up about it, I wouldn't even give it a second thought........my kind of rest.
