Not everyone will want the same quiver. There are a number of good bowquivers on the market. Each with qualities that will please some, but not everyone. Our specialty is making the best lightweight quivers on the market. Our basic 3 arrow quivers weigh about 3.2 ounces, and almost all of our quivers weigh less than 6 ounces. I don't think any other manufacturer can match that.
It's our goal at Eagle's flight Archery to make the best quality, ultralight weight quiver possible. (We make them specifically for those of you who want a quiver that doesn't change how your bow shoots.) We also make a variety of quivers in 4 different size hoods, 4 different hood designs, and for different applications including for takedown, side mount, two piece, and our latest one piece adjustable "Totem" system.
We are currently providing all of our limb gripping quivers with our "Talon" grip system. It is still very easy to attach or remove from your bow, but grips tighter to the bow than the original system. We think that it's a major improvement and have retrofitted a number of the older quivers with them at customer request.
In summary, it's not good quivers or bad quivers. It's what qualities are you looking for. You can't build a quiver like a tank and keep it lightweight.
