Thanks guys. All great points and suggestions.
I have chance to buy a rod. The rod is marked like a UL spin rod (1 - 4 pound test line), instead of Line Wt. like a fly rod would. But here's the twist...the serial # makes it look like a fly rod (w/ an "F" in the number). And it has a fly rod handle.
I've been collecting, buying, selling, using rods for 45 years, and I've never run across this before. I have one of the very same rods in a true spin rod model. So, that's why I was thinking about removing the fly handle and converting back to a spin rod...so I'd have a matching set of spin rods.
My guess is that it was a spin blank, that someone converted into a fly rod. I wouldn't mind having the rod stay that way, if it had the action and worked like a fly rod should. Any other thoughts?
