You make a good point, I've been in two minds. I'm going with a couple of mates, both of whom have been touring before (I haven't) and they've both said it's what they'll be doing, so I took their advice, in the end.
Uppermost in my mind is security, a nearly-new CT with givi panniers and topbox....I'm hoping the black cover will mean it's at least a little bit hidden. We'll be chaining the three bikes together, and I may even take the panniers and topbox into each B&B with me (all have private off-road parking) just to be doubly-secure.
For me this will be a test-tour, and will hopefully mean I'm better prepared for venturing further afield in the years to come. Touring was the main reason I bought this bike.
Anyhow, thanks for your thoughts guys.
