I've got one with Talas 32s on the front, its a great wee bike. There have been a few threads about them now so I figured I would reply.
The gripes you will read about are pedal feedback, low BB, and bushings. Pedal feedback is only an issue when you're standing up in the granny ring, it seems to be a bit of a trade-off because it pedals great in the 36, when you're more likely to be standing anyway. The low BB takes some getting used to but its key to the whole design of the bike, I haven't used the taller setting at all. Bushings, apparently these can be a problem if they're not maintained, mine seem fine so far and they are cheap to replace, full instructions and a spare set come with the frame.
I have had the bike since May, it has done the Ae Enduro, some big rides in Chamonix, and I am doing Kielder on it. It climbs and pedals great but the best thing about it is the descending, its really low and slack, light enough to pick up and pedal, and stiff in the rear end. It feels a wee bit like the Blue Pig with a bit of give in the rear end, which is exactly what I wanted.
The tapered head tube means there are loads of ways to build them up. I went for 140mm 32s because I wanted to keep the weight down and balance it with the 127mm in the back. You need to keep an eye on the stack height and A2C, if you put too much effort into lowering the front end you will lose head angle and drop the BB even further – the seat angle is nice and steep anyway. I think mine is probably around 29lbs with SLX, Crests, 203/180 rotors, Sunline V1, Wellgo Mags. The Crests seem to be holding up fine, touch wood.
