Of course im up for this and would go 2 up if required.
I still have all the various plans and routes if anyone wants them, personally i would not do Stelvio as its full of coaches and slow really not all its cracked up to be IMO, there are others closer and on the way such as Furka and Grimsel that are faster and more fun. I would also consider a trip on the way down through Mullhouse to go to the Schlumpf and possibly to Maranello while we are there.
I would also prob do a few more passes as we go down as well, but planning a route is fun.
And i am now allowed in Switzerland!
