so my choices are 1 out of the 3, Stelvio pass, Gavia pass and the Mortirolo. I don't have time for all 3. Not even 2. I only have time for one. I've seen and read the great battles of all of them. I will be using a 34 x 25/6/8. I wish I could spend my vacation riding all 3. But I have limited funds and limited times. So I have to pick one ?? Which one should I ride ?
