I have Rizoma Urlo on my SF848 I find that the slight curve of the grip fits the hand very well making them very comfortable.
Oxford heated grips on my M750 - they are a safety device as well as being comfy - your fingers can get to the brake lever much quicker when they are not frozen claws.....
I bought them from the design corse site but can't seem to see them on there now. The puig sites a bit confusing but you might have a bit more joy identifying them..
