I really would like to do it as it is meant to be in the rules, and as you set up the situation very well in my opinion, you should reap the rewards (I am not experienced in the way of sea lion, surely it can be done better, but the way you arranged your forces makes me doubt if sea-lion is the way to go for the Axis….especially since the die were quite in my favor in Europe, so far).
I need an hour or so anyway for the kid, maybe you find something definite until then. Only something that would support my view will make me do what I wrote below, every other result including none I will re-think my moves.
