Improved Disarm with a quarterstaff can be quite effective. Okay, so Strength isn't so good, but can still get reasonable bonuses on disarm attempt (+4 from feat and +4 for using 2-handed weapon) and no penalty for failure (unlike trip attempts).
Thanks for the reminder. I've been so focused on figting unarmed with my newly-created 20th level vow of poverty monk that I totally forgot about this.
Hmmm... +37 for an opposed attack roll is pretty darn good, even at 20th level.
