Yep. To expand on this, for big logs or when going uphill, I wheelie or manual and try to place my front wheel as close to the top of the log as possible. If wheelieing into it, I like to give a quick ratchet backward to level my pedals. Then using this as a base, I hop/lunge forward and try and place the rear wheel in the same place the front wheel just left. Shift weight back, roll out, and ride away. Much faster and smoother this way as opposed to slamming your bash/chainring and grinding over. It's all in the timing. Happy practicing!
edit: I totally missed sscyco's post - just do what he said.
