My friend just bought a Bowtech Carbon Knight as a backup bow and it shoots fine through paper with a $40 Whisker Biscuit rest. We put the Bowtech QAD Ultrarest Pro dropaway on it and can't get the left tear out of it. I moved it as far left as it will go and got it close but can't quite get it. I tried different spined arrows, too. On his Insanity, the rest had to be almost touching the riser to get a bullethole with it but we were able to fix that by adjusting the cam lean. The Carbon Knight doesn't have split yolks so there is no way to adjust it. He loves the bow but is considering getting rid of it if it won't tune with any other rest than a Biscuit. Anyone else put a dropaway on a carbon knight?
