Just my opinion
i don't like the spring arm quivers, single or double, because they end up marring the glass on the limbs wherever the rubber on the spring arms come in contact with the glass. Especially consider this if you are spending money to have BowDoc do his normally outstanding refinish.
Depending on how the frams sits on the riser, it tends to get in the way of my fingers.
I don't find that they have a real solid mount. The arms slip around.
For display purposes I guess they may be ok, but not to hunt with or shoot 3-D
A leather top quiver is not priod correct for that riser.
Others may have different opinions.
Just my thoughts
