Never heard of it will have to do some interweb searching.
Well...sounds to me like painting up some knights is a possible long-term side project. I like both the English and French miniatures. But I think in terms of ease of play for Lion's Rampant an earlier crusader period might have been a better option. There is a very clear distinction between full plate knights, sergeants, and the common foot. Whereas the Hundred Years War Perry miniatures are really only plated men-at-arms and then archers with their quilted and leather armor.
