Thanks for that, about what I hope for and expect to make good time round N. Wales at the start and know what to expect once I hit Ceredigion going south.
Agree with your advice for Matt, Pembs coast I love (especially from Cardigan to St Davids), but also found the Milford Haven section interesting in it's own right. Going round Castlemartin ranges was a bit of a pain, but enjoyed the live firing demo (from a distance)!!!
Well done on completion, I've done Pembs, Ceredigion and Lleyn sections over the years but would like to do the whole thing in a single shot. Maybe in 2015, but have to negotiate "time off" from home and wife!! Will be tackling it much the same as you with a tent and mixing wild camp, sites and possibly few B&B if I need a break (and bath).
For info, what daily mileage did you average overall, obviously it would vary a lot through sections, interested to know.
We've had the Nallo 2GT for some years, love it but can't compare it with anything else as it's all we have (apart from my Terra Nova laser comp - but that's different usage). I find the Hilliberg a good design and quick to put up etc. wouldn't swap it.
No idea regards foot space as I'm only 5'6" so never occurred to me.
