I think my sourdough starter is ready...

It's a bit livelier than I expected :-)
Still trying to find a recipe that works consistently.  The starter is good, but the end result isn't always good. 
Currently working on a 3:2:1 ratio of flour:water:starter, but it's a very wet dough.
The last recipe was 400g starter, 500g flour, 250 ml water, and that wasn't too bad, but the top collapsed.
Definitely trial and error.
