I have the all. All my personal rods have the carbon fiber handles. They do not chip, flake or wear out and easy to clean.
Next time we meet, I will show you a rod with them.
Hypalon, to me, is way too heavy for bass rods.
The other material, EVA, grips are light
I love Hypalon grips. Only issue I have with them are difficulty in shaping them. A bit more turning, but they balance the rod really well.
