I can't help you with your specific enquiry, sorry, but I thought I'd answer anyway!
I have no experience of any pads other than the standard Campagnolo pads. I've never seen any reason to stop using them. They fit the shoes and work well. I have absolutely no complaints about them. I use these:http://www.ribblecycles.co.uk/sp/road-t ... 0000000000
Why do you not use the Campagnolo pads? Am I missing something? Are others better?
