I bought the Duiker model late last summer and used this last Fall/Winter and its a dandy quiver as far as I'm concerned. After 26 years of using a bowquiver I've finally changed - I tried "Asbell type" side quivers a couple times and never liked the way they carried arrows - got in my way one way or the other.
I did a couple of additions to my safari tuff - covered the black material that is like nylon along the seam with stick-on moleskin to further quiet a very quiet quiver. I added a button over flap to cover the arrow hole when needed (never used this), added a quick release buckle on the strap like the bigger quiver has (never used that either). I added a thicker foam pad contact cemented into the bottom so that I can completely bury Snuffers in the foam (good addition) - this makes the arrows a bit harder to pull, but keeps them from moving and protects the broadheads from dirt. Never needed the rain cover, but it will come in handy someday. With the Duiker I put in 4 big Snuffers (or 3 and a judo) and get real nice clearance. I could stuff a few more in if needed, but I don't see a need for my use.
I didn't buy the Arrowmaster model because I pack a possibles bag and don't need the storage on the quiver, also I don't need the larger volume as I'm used to a 3 arrow bowquiver and never felt under - ammo'd with that hunting all over the US and Canada.
I'm VERY particular with my equipment, and the safari tuff is a very well designed, solidly built piece of gear.
