Seriously....there is no real bailing "technique." You either clear it or you eat dirt and take your chances.
IMHO Big Woody is just mentally intimidating, its actually quite easy if you just look straight ahead. On the other hand, it took me most of last year to do the filter with any level of confidence. The key to it is that when you lose momentum and feel like you are falling...don't try to unclip and "bail"---keep pedalling. You really need to keep your momentum up on the filter. It feels very counter-intuitive.
The only other advise I can give you is to listen to Master Yoda. "Try not. Do or no not." If you are approaching a feature and thinking about how you are going to bail, you are 90% likely to fall. Focus on what you are doing. If you fall, you fall. You just have to accept that you may fall, and forget about it and concentrate on clearing the feature.
