Cheers all, a wealth of info as usual. Boxelder, I've ridden a mates Roscoe, and it's definitely a nice bike, doesn't ride 'heavy', very solid in a good way. Can't buy one- he's got one!
The Meta test is complete, and unfortunately it's not the bike for me. I felt too far 'behind' the bottom bracket for efficient pedaling, and riding uphill felt like I was towing an anchor (even with pro pedal on). Rocky techy uphill was easy though, very flattering. Swapping back and forth between the meta and the roscoe the difference was clear on the long climbs, and I'm not willing to sacrifice that much for the benefits the meta design brings (very nice through tight and twisty stuff though). My mate even had to use the small front cog when he got on the Meta, something I've never seen him do ever, anywhere!
KMB reckon trek ex8/9.
Now I've got more of a feel for this full suss malarky, any others I should rule out (Zesty?) on the basis of the meta test? I definitely want to keep some of the saddle up efficiency of my hardtail when it's needed, like on long but non techy climbs, but also would like something forgiving/flattering when descending over typical steep rocky terrain. Not likely to be getting any significant air in the near future, except a few inches on whinlatter south loop :D
