ITT is (or rather was, until CV) on my radar, we've walked a lot around that part of the Pennines but only one or two bits of that trail. Excellent country for wilderness and solitude.
As has often been said here, the pleasure is in finding your own pitch on the day. Some of those hills are mainly grassy, though a bit tussocky, and a pitch should present little difficulty, but there is a fair amount of troublesome heather in those parts.
