I haven't heard of too many issues. My shop told me they are surprised that many are buying the Alley and Tribute over the Guardian so far.

One thing that really concerns me at Bowtech, and this is by all means no stab at them, is there may be a little quality control problem. With the amount of bows they're pumping out, its bound to happen. It just seems that most of the issues I'm seeing with the bows isn't a design flaw, but more along the lines of a missing part or faulty part etc. This is purely speculation though. Like I mentioned earlier, I've owned 3 Bowtechs and this is the first one that had any sort of issue.
