Weapon enhancements for a reach meleer

[KhaTheGrey]

I'm playing a hunter and a reach melee person at the same time. I'm looking for a nice enhancement to add to my lucerne hammer, in which I can somewhat control the battlefield with a long hammer and spike. :P

Anyways, best enchancement for me?

If you're using a reach weapon then Fortuitous is a good one. It adds a second attack at -5 to hit to on an attack of opportunity every round. It's a good way to get a pseudo-iterative on AOOs, and combines well with reach.
