Matt If you don't know the course I would stay away Or contact Andy and Marshal the first year(Like I did) or get out there with a map a recce recce recce. esp the bit from Mam Nick to the End, I know 'Skyline' had a wonder in the first half a few years a go but that shouldn't happen.
Typical Skyline weather then. Maybe next time T&C. Post it on Recces the day before you go out.
Vodaphone is pretty good all the way round, Not sure about any of the others.
