While we're on the subject . . .

I have a couple of these Delta Aztec Vibe gel pads on the way:

these are supposed to help hand pain/numbness/etc.

Because they will increase the effective diameter of the bars considerably, I'm wondering if the normal amount of tape provided will be enough. If not, and I have to use more than one roll per side, how do I make the "joint" or splice or whatever you call it . . .

Anybody used these?
