I've always used Yonex Supergrap, but I am leaning towards Tourna original XL. I don't sweat loads, but my hands get tacky enough. But even with dry hands, I do like the feel of Tourna.
I will probably have one gripped with Tourna and one with Supergrap, to switch if I feel the need. I am considering the black supergrap too, white gets grubby too quickly.
