Sometimes the question should be what kind of lure weights will be used.
This is what I'm thinking or along those lines of thought for a jigging rod selection.
Small lures of 1/64th oz. or lighter get an UL rod.
Lures of 1/32nd oxa. or lighter get a L rod.
Lures 1/64 to 1/8 oz. get a ML rod.
Lures 1/16 to 1/2 oz. get a M rod
Lures 1/8 to 3/4 oz. get a MH rod
Anything else get a H rod, unless you want get a custom made XH rod.
Then again one can always fish with any rod with any lure weight on it. It just helps to have the rod with the appropriate power to jig the lure with good control to impart jigging actions on it.
