I bought 3 different butt caps to try on two new casting rods I'm building and now I can't decide! What do you think or have you had better luck with a particular material for butt caps? Rubberized cork, plastic, or EVA?

I like the rubberized cork the best then the plastic. Just my opinion.

I like EVA, the rubberized, then plastic.

Rubberized cork is my favorite too.

Prefer rubberized cork

Rubberized cork for me.  I think its durability is bulletproof.  There are too many kinds of plastics, some good and some bad, and you cannot really tell what grade you are getting.  EVA may be as durable, but in the old days it was not.  Since it is a plastic, at some time one would expect the UV to get to it.  Not sure today.  And I don't particulary like its look, but that is just personale taste.
