I built my first bow almost 50years ago and I've been making my own sights and rest for the last thirty years. I use the whisker biscuit because it tunes easy it stays in tune and it doesn't bend, break, or go out of tune. You can tune any bow and rest combination to work if you work at it, its just a much more streamlined operation with the biscuit. Some folks just can't seem to grasp this concept but its true. Lots of people have tried to just swap in the biscuit for their old rest without taking into account where the bows tiller might be or what the effect of very high nocking point would have on their results. These people would, quite predictably not have stellar results with the biscuit. Some shops have their own bias against the biscuit and they propably won't know how to make it work either because they don't want it to work. I wouldn't trust the people who don't want the biscuit to work to fix a drink! This rest is the best archery product to come along in years and if they can't see that they can all go piss up a rope! Good luck hunting!
