Safari Tuff all the way. I've spent a small fortune on different types of quivers (including the CQ--III, I think). There may not be one quiver that is perfect for every different situation, but the Arrowmaster is as close as you'll get.
If you need to carry stuff, use a fanny pack, back pack, or frame pack--the ST quivers work just fine with any of them. If you like to hunt from a stand, just bungee the ST to the tree like you would any other. If you are roving for bunnies or grouse, cram it full and take off. If you are travelling through thick and nasty stuff, you can slide it around to most any position and get through without snagging or loosing an arrow.
If can afford only one quiver, my suggestion is ST. If you can afford multiple quivers, the ST should be one of them.
