If these are the RodWraps he was talking about, then I know they are used on golf putters and tennis racket grips with success. The only advantage I could see over cork grips on rod handles is you can color code your rods. That's assuming you have enough of the same identical rod/reel combos to color code. Too bad they don't have pink, cause Delw would be all over them.
Aw jeez that is ugly, da I use a 3m tape from Home Dump to indentify my rods on the saltwater trips, makes it easy to find my rigs when there is 200+ rods and reels on a boat. I don't wrap the handle just the rod at eye level (Stand Up) Can't think of any use for bass fishin though.
