You've probably already seen it but there's a Ducati raised seat (not Touratech though) for the 1200/1260 Enduro. It's 20mm taller and claims, according to the blurb, to improve comfort... There's a part number on the page linked to above, might help your search for ones locally if it's of interest.
Hmmmm, thank you, wasn't aware of that. I could easily accommodate an extra 20mm (long legs) but doubt it would do what I seek, i.e. a comfortable place to park my arse ...
