gbowen, thanks for mentioning Bloody Big Battles.
BBB was actually originally designed for FPW. The rulebook includes a 9-scenario episodic campaign of the biggest battles of the war. About 8 or 9 more scenarios are freely available from the BBB io group files. For collected reviews of BBB, see here:

Eleve, I see you're in Yorkshire. Any chance I can tempt you along to our BBB Bash Day convention in Sheffield on Saturday 27 June?

It'd be a great chance for you to get a taste of the game. (I'll probably be running Coulmiers.)
And/or, you could meet some of us and roll some dice the next day at Joy of Six, also in Sheffield, Sunday 28 June:

Anyway, I applaud your idea of getting into FPW. It's an underrated period – some people are put off because they think it's too one-sided, when in fact it was far from a walkover for the Germans and there is lots of interesting action to get on the tabletop. Best of luck with finding a ruleset that suits your taste.
