From a performance standpoint, do you prefer split grip or single gripped rods. Also, cork or EVA foam?

Split grip and I prefer Winn Gripps on my reaction, fast moving baits. You can look up fx custom rods and read about the differences. Or pm me I will send ya a link.

Split eva-don't like those only have 1 rod with these

I think I prefer Winn over all others, then it's kind of a toss up.  Prefer the look of cork, but the feel of good quality EVA.  Full vs split, don't too much care.

My preference would be full cork.

Split grip cork for everything but flipping, flipping I'm full grip

Casting rod full rear grip cfx carbon.  

Spinning split grips cork.

Got no time for Eva hate the feel.

I appreciate well implemented EVA, synthetic and cork composite handles.  But, I'll take cork over cheap EVA.  Split or full depends upon the execution and ultimately the "feel" of the particular rod.

Spinning split grip always, casting is 50/50  cork 100% of the time. I like how it ages and also how you wear into them.

Split/Cork is my preference but not a deal breaker. 

I voted for the EVA foam, though I actually prefer the material St. Croix uses.
