I have little rod building experience so I have no clue if this is a stupid question. So I was going to build a Rainshadow Switch 6wt and than I found one already finished at a great price and snatched it up late last week. The problem is that the rod was built for saltwater fishing and the handle is pretty much only meant for overhand casting. I fished it a couple of days this weekend and was missing a fatter section of cork at the top of the handle to get a better grip on the rod during spey casts. Is it possible to carefully remove a section of cork from a finished handle, add a fatter ring and than sand the whole thing even again and have it look good? If not, I can live with it, just thinking about doing a mod like this in the future if it is feasible.
