I shoot with a whisker biscuit. I am realitively new to archery. There is not a pro shop anywhere near me and I set my bow up by myself. The only help I have had with tuning is the information I have gotten from the great people on this forum. I got my whisker biscuit last year on Father's Day and had it trimmed and tuned in about 30 minuits. I have not had to adjust it since I put it on. I also use 3 four inch feathers fletched with a left helical and have never had a problem with the biscuit wearing out my feathers. The only feathers I have had to replace have been damaged by other arrows. I swithed from a prong style rest because I was having to spend too much time tunning it It seems like I was adjusting it about once every week or two. you really cant find a more economical or dependable hunting rest IMHO.
