Thanks for the encouragement guys.
After reading a bit more about Frostgrave I can see me using the LOTRS figs for that game as well (if I can find a willing opponent), I was intending to use my Mordheim stuff but Frostgrave appears to be an early mediaeval setting so the LOTR figs might be more appropriate.
It seems both games, Lion Rampant and Frostgrave, have broad generic troop types so people can use whatever they see as matching the stat line and equipment.
Just in case anyone missed the latest issue of Wargame, Soldiers and Strategy (issue 79) has fantasy rules for Lion Rampant, they keep things quite simple adding rules for flyers, magic and the undead.
Edit: Changed the name of the thread so can lump all my fantasy stuff in here. Added my Mordor/Angmar forces to the blog:
