Great topic.

Some things that did not pan out for me:

-Bowmaniac Stabilizer -- looked fantastic, didn't meet my expectations in performance.

-Drop away rest (in general), I still use my ARC, buy have since gone back to regular rests on all my other bows. Anytime you have to change anything with most dropaways, it is very difficult to get it to come up and drop exactly as you had it before.

-Stan Rattler head -- makes the release too long and I found other BT head to work better.

-API treestand -- really liked it until I got my Lone-wolf Alpha climber.

-Morrel ss target bag. Bags cannot take repeated arrows in the same place -- shoot throughs happen rather quickly, Can't shoot many 5-spot or 3-spot games.

-Single cam bows (I still have 1 and still use it for hunting). The only benefit they have that I can see is they tend to be a little quieter.
