RE: whisker biskit
ive converted everyone i hunt with to use them (8-12 people) all of us shoot great to at least 35 yds many dif types of bows and arrow set-ups. no problems just get it set where the rest should be. but i def recomend feathers just fall through the rest so smooth. i shot mine for over 1500 shots then replaced them just because i had the time. if i didnt have that on id go with the old TM hunter just because the drop aways are such a risk for something breaking or getting stuck and most flop the arrow around thats why everyone puts fleece tape all over the bow with them on.
