Thanks and LOL - Actually I am riding my FG now with the wheels of my roadie :-), not the ones pictured.
When I tried to ride to work one morning, after having a nice evening ride the previous day, I discovered the flat in the front (I am running 23x700 Kenda's on FG) so easiest way to go was to borrow the tubular front Shamal from my roadie. You would not believe, but the same happened the following day - this time the rear. Since my rear Shamal had Gipiemme casette body (for 10x drivetrian compatibility) anyway and since I just have finished the adapter to fix the Campy wheel I used it.
BTW
My FG rear wheels are real abominations - they are all dished

Yet it allows for a great flexibility - I can fix all the wheels I use between FG and a road bike: pictured in FGG Gipiemme Grecals (so, so and noisy b/c of very stiff rims and high spoke tension), beautiful and fast silver 12 spoke Shamals which originally were 9 speed, as well as black, 10sp 16spoke Shamals (strange the rim profile is different then the silver one, also internals of the hubs are different).
The adapters grab the casette body by the way of a piece of an old cog fitting the splines bolted permanently to the adapter and they are fixed to the hubs' bodies by bolts.
Perfect chainline each time
I am using Uniglide cogs which fit the bodies two ways and are less likely to throw the chain then HG ones. I tried to use dedicated SS 18T cog fitting the splines, but it was crap.
