Any reason why these would not work?  The Winn golf grips are half the price of their fishing grips.

Probably have to cut them to fit.  Measure twice ( or three times ) cut once.  Tennis racket grip tape works good, lots of colors available on line - not so much in the sporting goods stores I frequent.  Baseball bat grip tape comes in various thickness and the thinnest works good.  The ball bat tape is a little bit spongier than the tennis raquet tape.  I've often thought that bicycle handle bar tape would  work good but I never seem to get around a bike shop when I have that idea.

Golf club grips are very thin compared to fishing rod handles and I could not fish that way myself. I don't think they would wrap around the handle, then again I've never seen a bare rod handle.

 

My Dad had some really fat golf grips because he lost some use in one hand. They still weren't fishing rod size. They were tapered too and not in a way that would promote a comfortable grip for a rod.

 

Have you ever held a golf club? I don't think they'd work well, my opinion.

Only way your going to know is to buy one, or go to a golf shop and look. The underlying EVA material comes in different hardnesses depending on the application, that's important for comfort.
