25l was fine for me, but it depends how bulky your stuff is.
I would have thought so, yes. Although , as mentioned above so much will depend on your equipment (bivvi or tent/ Sleeping bag, etc). Given the fairly negligible impact from weight diff (small/large pack) over this distance/terrain. I would say focus more on ease of access in very bad weather.
Hi jo if you want to borrow any stuff for the race or to test give me a shout :-)
I used a Lowe Alpine LiteFlite 25 for the Challenger this year which was perfect. Remember, the smaller the pack the less opportunity there is to fill it with extra unnecessary stuff "just in case"!
Another vote for the LitefFlite, the OMM front pouch fits quite well too if you are happy to use the 'waist' strap to anchor the bottom of it. I can't manage accessing the side pouches when wearing it though.
Has anyone used a UD Fastpack 30 and if so, how did you get on with it? Did you find a compatible front pack?
I have the Fastpack 20 Jo and the salomon front pouches I have ordered will arrive in the next few days so i will give you a sitrep once I've trialled them

Ah cheers John... that would be great.
What are your thoughts on the Fastpack in general?
Only arrived Wednesday and I'm laid up with flu so haven't had it it yet. First impressions? Good quality, good use areas for pouches etc I'll keep you informed as to how it goes mate
