Hey Trevor,
Im not sure what the norm is but using some very valuable fore thought i decided to buy one light spin, one light baitcast outfit, a heavy spin and baitcast, 2 beach rods (one heavy one light), a heavy overhead for boating and am now in the process of aquiring a fly fishing outfit.
Why the forethought? Because I bought the best of the best and have a purpose for every combo. I have no unused rods sitting idle, (bar the ragoon stick my grandfather built!) and intend to make em last.
Cheers,
Bobfish
