I'm going with the Tufftrax, but am having a crisis of confidence about my semi-slick 1.9 Panaracer Mach Ss tyres. I'll still take them though, in case I wish to press on to Crask on Sunday and cycle the rest of the way home on Monday. Then cycle to Stromness to get my car on Tuesday.
What tyres are you guys using?
My panniers are DHB waterproof roll-top Ortlieb clones, which have the essential heel clearance. Re the Altura Universal panniers, they should work anywhere in this, and other, solar systems. Singularities such as black holes or magnetic monopoles may invalidate the warranty. The Alturans must be an advanced species to have developed such sophisticated pannier technology.
I assume bedding will be provided at the 'Youth' Hostel. I'll be bringing a book for a quiet night in after the days cycling.
