I've got several hundred shots through my Allegiance now and the only stock silencing device the has broken off thus far is the one on the cable slid. However, I'm not sure if I accidentally ripped it off somehow or it actually fell off from use. In any case, the rest of my hush kit is in perfect shape still. I wonder why the rest of you guys are having trouble with it.
As for accessories - it's up to you. There are a ton of good products out there that work great, you just have to decide what features you're looking for and what type of budget you're on. Personally I prefer a shorter stabilizer for hunting purposes, but there are plenty of guys out there shooting long ones who kill more stuff than I do. My bow is set up with a set of Limbsaver ultras, a Cobra Sidewinder sight, NAP Quiktune 360 rest, 6" Stealth stabilizer, and an Alpine SoftLock Quiver. I truely could not be happier with the way it shoots and has performed thus far.
