I just got in a Kanati Dual Arc. It seems exceptional in every way to me, and not just because it's new. I've looked at and tried out various makes/models at the local shop and the Kanati was the best out of the 6-8 that I tried.
It's adjustable (for mounting position, balance, location of arrow heads, and location of arrow nocks), lighter than some and not much heavier than others, very stable, easy on and off the bow, looks great and can be dyed to match your bow, is made sturdy and right here in the US. It's just the best design in terms of versatility out there right now. Also, for what it's worth, my bow actually shoots better with it on than with it off; my bow in now more quiet, more stable, has less perceived hand shock, and the top tip rolls back into the arch of my hand after the shot (adjustable balance point due to dual arcs) allowing me to not grip the bow at all and still not loose it after the shot.
