Opinion please on seat 9L? Aerolopa seat map shows that the toilet is right in front of it, but I'm assuming that I won't notice very much, being tucked away against the window?

Okay, I've now found commentary in the first pages of this thread which seem to endorse 9A and 9L as amongst the best choices. I asked the question before manually reading the thread (there's 94 pages on this thread now and it is not possible to Search for "9L" or "9A").
So it seems I have scored well!
