Lennie in Md: My biscuits have never iced up with or without the "No-Snow" on them. The spray does work real well on feathers though, it penetrates the fibers of the feather and doesn't allow water to penetrate the feather. There may be other uses for 'No-Snow" besides feathers. I sprayed the bathroom mirror with the stuff and buffed it dry and the mirror didn't fog after running the shower for five minutes. Maybe it can do the same for eyeglasses or the inside of the windshields on our trucks in the morning. As far as my compliments on the biscuit go they are all true. I have never torn a feather or a vane because of the biscuit and the biscuit is just as accurate or more, than any other rest out there. I have had other rests bend, break, and drop my arrow and none of that has happened with the biscuit. The whisker biscuit is solid in its design and it stays in adjustment. If you simply bend the bristles of the rest occasionally while you are hunting you will know what its supposed to feel like and maybe gain an insight as to how often and under what weather conditions you need to do this. Basically whenever you feel the need to move and breakup the ice that forms on your clothing you could check the biscuit too. The biscuit has consistently been a very durable rest for me. I've pulled the rest through briars, grape vines, and tree branches and its never bent. broke, or gotten out of adjustment to foul up my shot. In the past I've purchased enough moleskin and tape to make rests work that I could probably have made a new seat cover for the truck. The biscuit works right out of the package without any tape or moleskin. The biscuit lasts for thousands of shots and if you want to change biscuits or substitute a real soft quiet well worn one for hunting the bow is still going to be in tune. The whisker biscuit tunes easier than any other rest I've tried. There are no clicks, whacks, or bangs when you tune a whisker biscuit and no foot powder either. The biscuit will not cure poor form when shooting a bow. The biscuit will not magically fix a bow that is out of tune. On a properly tuned bow shooting the correct spine arrows the biscuit is a very accurate, quiet, reliable, durable, and long lasting rest. I got no complaints with any of my whisker biscuits, anybody that has a problem with the biscuit is probably doing something wrong. Good luck hunting!
