I have shot them all. In the last two years, I have shot a QAD HD Pro (loved it but the wheel hit my thumb), Trophy Taker (Pronghorn and FC), Limbdriver, Ripcord and a few others. I just put the WB on for hunting season as I always have. I have experienced a 3-4 fps loss. Not enough for me to go away from it for hunting. The Octane Hostage Pro is nice. Replacement bristles are expensive! And you will need a lot of them. I have heard of using superglue as a trick on the bottom bristle though.
