Jon here. Please send me your e-mail address and I'll send you a bunch of photographs of the after market QAD Arrow Rest that replaces the Whisker Biscuit. My e-mail address is: firstname.lastname@example.org
Mine was a prototype, but the maker has since began producing and selling plenty of them. Once you make the cut over you'll never look back to the old rests.
I just finished tuning my TAC15i for broadheads, since hunting season starts here next week. I'm using the Phat Head Broadheads, but I can probably tune for almost any head with good accuracy. My point was that I'm able to consistently hit a 1 inch florescent dot at up to 70 yards. The only reason I'm stated 70 yards is because I haven't shot at a longer distance yet because my property only goes to 70 yards, so I would need to go elsewhere to shot further.
It's not instant and it's not automatic. There is some additional tuning work involved, but the accuracy is worth it. I can easily shoot 3 vane or 4 vane configurations and in moments adjust for either. The rest has no wear points, so once you are tuned you're tuned until you break something.
P.S. RMB and Super 91 have also made the switch to QAD Rests. There are others as well but I don't maintain any type of lists or records on how many.
I don't recommend making this change until after hunting season because it will require a week or more before you are fully up and running with the new set up.
