I forget the name but I just used a killer cotton bar tape with the silicone backing myself on my Centurion, my boss said it was a new product he just got in and I really like it. I am getting it in blue for my wife's bike and will use it on all of my road drop bars. I always liked cotton wrap and this does add the padding that feels just right to me.

EDIT the stuff I used was from Rav-X and I think it was Cotton Gel or something like that.
