I use the 2 piece Octane Quiver and though it was a little pricey, I like it! I love the concept of the magnets and the silence they give without dulling your broadheads. I also like the adjustability of the unit.
The only downside to the quiver, is that those magnets do make the quiver a bit heavier than my $20 dollar detachable quiver. I just kept the mounts from my old quiver on and if I know Im doing a long hike, I can detach the Octane and use "El Cheapo" to reduce the weight.
Hope this helps!
