Switching to T5s worth it?

[ReefFreek917]

I have over my 75g 2x400W MH driven by 2 magnetic ballasts and 2x54W T5 HO actinics driven by a Workhorse ballast.

I am thinking about adding 4 more 54W HO's with Tek 2 reflectors and a Sylvania ballast and removing the MH. I want to cut my electric bill down a little plus I wouldnt have to worry about heat. I have a lot of softies, some SPS, and couple clams.
Would the T5's be enough?

I love the look of my halides but I am tired of paying for them.

What do you guys think? Suggestions on bulb choice would also be great.

Thanks guys!

Ask Grim in the lighting forum - there is a large T5 thread. 6x54W T5's should keep most things, but the clams, especially if down low might need 8x54W.
