don't think about it - if I'm going down it's already too late & the side I'm going down on can't be changed.

If you realise yr losing yr balance & have time to decide would it not better to put a foot down ?

I fell quite a few times when I started with clipless, if I lose balance now one foot seems to come down automatically - which is good cause it looked so naff losing yr balance & just tipping over with feet stuck to the pedals...
