I'm not a fan of mediation in these situations. Here in the US the mediation would be some clown who knows nothing about us, the facts of the case, and likely even the law. We pay said clown about $5k for the day. We each pay our lawyers, I'm estimating $2,400 per side to attend and likely another $3,000 to prepare in advance and do the mediator's statement. We sit in different rooms and the clown passes our demands back and forth. No thanks.

I like the second option. He says he wants to wrap it up. He filed. Much cheaper and more targeted. No need for all the mediator games.

I could have written your top list verbatim. The second one would differ.
