Rack,
I used one for about a year or so awhile back, and thought it was a great rest. I swithched to a drop-away when I started shooting 3-D shoots. As far as tuning goes, you would think that any rest that comes in contact with all three of your vanes would be hard to tune, but in reality, it didn't tune much different than my drop-away. As far as quietness goes, I think my Trophy-Taker is actually a little quieter, as long as you have the V-arm covered with felt. Since the bristles on the Whisker-Bisquit rub against the arrow at a 90 angle, you'll have some noise all the way from let-down up to full draw, and aluminum arrows seem to be a little noisier than carbons. Hope this helps a little.
