I have a whisker biskit on my Q2 and I really like it. New style that knocks just as fast as any rest and is absolutely silent. Chrono shows it only slowed the arrow by about 2 fps. Not enough in my opinion to make any difference. Deer will jump the fastest arrow, especially if put on alert by an arrow that hisses/squeaks on a rest or that thumps a riser when it falls off the rest. Neither of which are concerns for me now. Seems to shoot just as accurate as my old 2 prong style. By that I mean I am hitting ping-pong balls at 20 yards. I have bow hunted for over 20 years and was skeptical of the biskit until I finally tried it. Drop aways have too many moving parts for my liking.
