Thanks mate - yes good suggestions.
Have now had 5 games in a row where I haven't drawn a stormer till site 7+ (and not a single one in the game just played!).
Even accounting for gemps sometimes "interesting" shuffles, that tells me I need to cut the size down a fair bit!
Will give those a go and see. I'm a bit wary of going down to one of the bows in case of corsairs or dunland but I do think ultimately this will get more wins if I can get it down to more lime 34/34.
