I will be having a look at a modded seat pad in the next few weeks, but don't have any details of who made it and how, as yet. I am told that it is taller than the standard pad, so I thought it might be relevant to your query.
Oh. Having re-read your original post, I don't know that it is the same as the ones you saw at Pro V Twins, so what I end up with may be irrelevant to you.
I'll get me coat!
