[SPOILER] Do you use the Three Sacred Treasures when redoing Ch.9 and 23?

Despite the fact that Ch.9 had pesky Ornes in high level playthroughs (I think as low as 6.5 or 7 - my highest for Ch.9 is 7.0 iirc) I usually stay with my own weapons. Makes for funny dialogue in Ch. 23 with [abbr=Hades][][][][][][/abbr]'s 'bad breath' instead of shredding the Treasures, but also makes fighting a lot more natural (apparently the Light Arrows are pretty damn weak when you compare them to more powerful personal weapons).
