MH watt selection?

I am planning on upgrading my lighting and would like to know if I should go with 175 watt or 250 watt MH. My tank is a 46 BF which currently has a single 150 watt MH and 2X 65 watt acintics. I will be upgrading to 2X 20000k MH with 2X 55 watt 10000k CF. I currently have a mixed reef but I am in the process of building a propagation system so most of my softies and LPS will go into that and I will be left with my SPS and some zoos.

So should I go with the higher watts since it is not that much more expensive, Or will that much light be over kill?

If you're going with 20k bulbs, I'd shoot for the 250W. 20k bulbs have less light output than 175s.

Its not much more expensive except in utilities
