Why do we call it a quiver?
An archer wants all the arrows in their quiver to be as close to identical as possible. Obviously this in not the case with skis (except maybe a racer that has several pairs of identical skis).
A golf bag is made up of different clubs, each one serving a specific function with varying degrees of overlap. I believe this resembles skiing more than the term quiver.
And it costs a lot of money to have a complete set - Driver to putter.
