Some of the best sps I have seen around here are owned by a man who run a coral store and all he uses are T5HO.
His display tank has the best colors sps can get.
Maybe your sps has other issues than just your light?
BTW, I use a 250 watt MH on my 75 aquarium and with just 4 little fans the temperature rarely go higher than 78F. Most of the time it stay at 76.5 set by my controller. Of course we run AC in the house and it's not for the aquarium, it's for our own comfort. I cannot stand the heat.

I find that SPS doesn't do well with just T5's (others might weigh in differently, but that's my finding).
As for wave motion, I have MP40W and find it's great for my needs. Hydor's are kind of bulky and the prop breaks easiliy. They don't have anything near of the output that the MP40 does. If you got the bucks go for MP40.
