Has to be cork, full length on casting, which is what I use the most. Two piece rub me the wrong way..... Literally. Maybe its just my hook setting style, but I absolutely hate split grips on casting tackle. Spinning is a wrist-set for me, so I really don't care either way. Cork is more sensitive than foam and is simply better looking. The new rods are just like Muscle Cars, you can put Mags, six exhaust pipes, flames, and the whole nine yards on a Challenger, but in time what people really want are the stock, pure cars, not the hyped-up ones that are miles from number matching.....
