Are you just referring to SMP in general, or that particular one? My line of thinking was, buy this for almost nothing. If it turns out to be the holy grail that others talk about, buy a nicer one / many for all my bikes. If I don't like, it will be on offer here for £6.
Just ordered one of these on the continued quest for comfort. I do find the prices unbelievable. £13 for an SMP copy to my door from 6,000 miles away.

If my bottom agrees I hope I can get the artwork off the leather though. Will acetone be my best bet?
