i did until a year ago......used them for 10 years. i think whisker biscuits are great, and you can be accurate with them even at long distances. i remember watching youtube videos of a guy shooting with a biscuit at 100 yards to prove you can be accurate, and he sure as heck was. however if you watch the fletchings go through the biscuit at slow motion it is a pretty violent reaction, and i would think you would definitely be more accurate than not without having that type of contact. the nice thing about a whisker biscuit is it is pretty much worry free, the bad thing is, if you shoot often, you will need to replace it often, not to mention mine used to get tore up by brush, i think i replaced more from that than shooting.
