tim, yes I've sussed that line out for that corner - and I think the other key point is to go as fast as possible whenever approaching these rooty sections so the bike skims over the bumps. I should add that I don't often think about what I'm doing when riding the trails, but afterwards I'll often think about any particular segments where I either wasn't keeping up with someone or had someone hard on my tail - I know I can't expect to be faster than everyone but if someone is quicker I like to work out why so I can get quicker! herman, I'm running lower pressures in the wet and mud, about 20/24 F/R. When I find some spare time we shall have to hook up and see if we can make each other corner better - some daylight and videoing would be useful...
Van Halen, I've been thinking about your 'feet up and ride it like a pump track comment' - a few rides back I wore contacts rather than glasses and noticed it made me more confident about my line choice and better at looking ahead. My guess is that having useful downwards peripheral vision rather than just shortsighted blur meant that I could subconsciously confirm I was riding the right line - and when you're relying on the natural ruts to create a berm the difference between using the berm and pulling some G and being off over the edge, losing grip and sliding into a tree is only a few inches.
Not sure about moto or MTB style body position - will have to practise with both and get a feel for how to move fluidly between them as conditions change. Gut feeling is that the looser and slippier it is, the more moto-style will suit, the rougher it is the more MTB-style will suit, especially with no rear suspension.
I know to many it probably seems like I'm thinking too much but I'm not a natural sportsman - however I'm quite good at self-coaching. I'm not a brave rider but once I've worked out how to do something better then I'll commit to it on the trail, turn my brain off and get into the flow. Not dissimilar to how I learnt how to play bass years ago - lots of thinking and practising but then when it's time to rehearse, perform or record, it's all about letting go and making the groove happen.
