I hate when the reel seat and the foot don't match. This is more common than people think. They should come up with tighter controls on how these dimensions are made.
What if reels within a given range of line weight designations used a standard footsize, and the rod makers also stuck to it by line weight? Also, a replaceable reel foot would be nice, anyone ever hear of one?
Most of my reels and rods match up, but some don't and over the course of a day's fishing it can drive you nuts.
