3.5e Crusader Multiclass help

[Clammyhands]

Fairly novice player here, currently playing 7th level Crusader tank (originally intended on going straight crusader 20) and would love some input on multiclass options for my character. Mo9 and RKV certainly interest me but I'm not quite sure what would be the best entry into either considering my level. Any help or other ideas would be much appreciated.

Friend of mine just went into Fist of Raziel, but had also multiclassed Paladin and Cleric as well as Crusader.

Get one level of Binder from Tome of Magic and five in Hellreaver from Fiendish Codex II. Bind Naberius for the Fast Ability Healing ability, and heal 10 damage to anyone within 20 feet every round as a swift action. After that just take more Crusader, you'll still have 9th level maneuvers at 20th.
