Lots of people overreact to steepness and sit right on the back tyre, like they want to be on the cover of MBR. Almost never neccesary, certainly not at inners, but it destabilises the bike and robs you of front wheel grip. So if you’re doing that, don’t. The idea is to be kind of above the bike, not behind.
Other’n that… It’s useful to know how much grip you have. At the bottom of Gold, frinstance, unless you’re cranking it it’s completely possible to stop, trackstand and restart (had to do this in an enduro race there once as a couple of people stacked right in front of me). Not that this is usually a good idea, but once you’ve done it once, I find it useful to know.
