normal handle or split grip

[DVT Mike]

Cork requires a fair bit more maintenance than EVA and is much more expensive. The original purpose of a spilt grip was to consistantly place your hand for two handed casting with some weight saving as a side benefit. Now I think in production rods it's more about reducing material cost and the style aspect.

There is a frequency measurement a s part of the Common Cents system but that's geared more toward recovery speed of the tip which I suppose translates to sensitivity at some level. I'm just now delving into that whole subject.
