[Closed] Sella Ronda MTB - anyone done it?

We've booked a couple of weeks in the Dolomites and I fancy doing the Sella Ronda MTB 'Tour'. Just trying to work out which bike to take - lightish 100mm FS or slightly heavier and slacker 140mm FS. The 140 is only 2.5 pounds heavier, but its not exactly the perkiest climbing bike. Has anyone on here done the Sella Ronda MTB? If so, which bike would you go for?

(looking at photos and Youtube vids, a lot of the terrain doesn't look it'd really warrant a 140 FS - but y'know how misleading helmet cam footage can sometimes be).
