Full sussers are so capable these days that – unless you’re a demon on the climbs – I’d be focusing on something that climbs well rather than going too “all mountain”. For every down in the Peaks you’ve got to slog up something first and the easier that is the better. I’m not suggesting some lightweight XC whippet, but the modern breed of 120 – 140mm ish full sussers are more than capable downhill.
Personally speaking I’d urge you to demo some rather than buy mail order, since sometimes what looks right on paper doesn’t suit you to ride. To give you an example, I bought a Transition Bandit earlier this year. On my shortlist was a Yeti ASR5 too. I thought the Yeti would blow me away, being light and stiff, but actually I didn’t get on with my demo ride at all. I just couldn’t gel with it. The Bandit, surprisingly, was much more capable uphill than I expected and is still more capable downhill than I’ll ever be!
[EDIT] – don’t dismiss the ubiquitous Orange 5. I demo’d it and loved it. The main reason I didn’t get one was the fact they’re a bit – um – common. Granted you might have to snoop around to get last season’s for your budget
