First off Congrats on the second copy of Michael Lance. It's one of the best Light Lances in the game as it's the only FLB capable one with Defender in it. Very valuable lance and definitely one that you should be FLBing. Definite priority over Tish's as hers doesn't become good until November (when it can be FLBed, and it still doesn't get Defender). The Longinus is Assault/Rush, Lugh's Lance is Assault/Elaborate, and Tish's is Assault/Exceed/Ascension.
