Tourist, who knows. I can only go from my own keester experience, but my feeling is that you'd have to be hammering more to take weight off your tukus.
I took the c17 off my bike last year to have more comfortable long rides with the b17 I had kicking around, but who the heck knows for you.
Fancy assed bike shorts ain't cheap too, so it seems that in the end, we all take a monetary risk when trying out new stuff.
I was lucky when I got my first nicer padded shorts, and then stuck with getting the same ones (newer model actually) just because "if it ain't broke....."
