What rules to use with Wood Elves

I am just about to purchase a collection of wood elves from a fellow club member, all old citadel stuff.  I will have about 90 infantry, 8 cavalry, 3 hawks/eagles with archer crew and a tree man ent type creature

Forces for Hordes of the Things and Dragon Rampant are very doable but I wondered if anyone had suggestions for other rule sets that might be suitable?
