Sorry, ivor, been away so haven't had a chance to reply to say that your commitment post made me giggle.

I'm just so the other way round. The knowledge that I've gone out and got fresh yeast that needs to be used, can be killed relatively easily and has fairly precise timing requirements makes me shake. Sammy (my starter - easy name since he's named after Sourdough Sam who is my NFL team's mascot) just needs taken out of the fridge and fed the night before before hibernating again.

This weekend, I'm at home so if the weather isn't great, I may give the yeasted stuff a try.
