I have one on my Allegiance shooting Gold Tip 7595 Pro-Hunters.......so far so good but I haven't been shooting that bow much beyond messing around.
It's still the hot and heavy 3D season so I won't get to really evaluate it for a couple weeks yet.

So far it seems very quiet and consistent but I also want to try the Muzzy Zero Effect "Next Gen" for parallel limb bows on it as well. I loved my ZE's for the years leading up til' the limbs really started getting laid back and they became a pain to tune. Now they have one that apparently compliments today's extreme limb angles and low slide travel so I want to try it as well before I decide on a winner for the season.
