a lot of people say "go MH!" and i bought into it.
but honestly, if you are keeping an exclusively LPS tank like I am, you will not want 250w bulbs. I'm thinking of either trading the 14k hamilton bulbs for 20k XM bulbs. or selling everything and getting a T5 setup

Not with 14K hammies. Those bulbs aren't particularly powerful, so you should have anything burn. If you want to save energy, run a shorter photoperiod. I think the 14K hammies are excellent bulbs for LPS. I couldn't stand them over my acros.
Oh yeah, acros grew well with a 8hr photoperiod, same setup. I would try 4 to 5 hours.
