Are you using the Complete Warrior Samurai Variant? I've never liked it. 'Cause it's really not that good.
I tend to avoid dipping into multiple classes. I like playing characters straight through, or possibly with a nice prestige class to round them off. With the Tome of Battle and PHBII out, I really want to play a straight fighter, since all the new feats give them so much more options and let them compete with full casters at the higher levels.
