I think Cinelli cork is

I think Cinelli cork is still the best. This looks and feels great, and wears well. It's adhesive-backed so it won't slip. My only complaint is that the length of each strip isn't more generous. I have 44cm bars (c-c; 46 to each edge) and had to wrap a bit sparingly toward the top so as to not run out of tape.
