Crusader is, by far, the best leveling enchant you can put on your heirloom weapons. It's 100 AP until level 60, 60AP at level 70, and 20AP at level 80. So yeah, in northrend Crusader is pretty bad, but for almost the entire time you spend leveling, Crusader is awesome.
Furthermore, that's not including the self-heal effect of Crusader, which is fantastic for reducing downtime while leveling.
Double WF, Double Crusader is the way to go when leveling Enhancement.
