How much light?

I'd like the lighting to be able to keep anything: SPS, clams, etc. I know...MH's. Had them, wasn't happy.
I currently have 4 110watt VHO's over a 75 gallon tank.
I was trying to sell the current system and replace it with 4 T5's powered by an Icecap 660. I haven't been able to sell the lights I have.
Would adding 2 more VHO's be enough? Should I add 2 T5's powered by a T5 ballast? Or, if I add the T5's, would I need to overdrive them off an Icecap ballast?
The 2 T5's off a T5 ballast is the least expensive, then the VHO's, then the T5's off the Icecap. I'd like to spend the least possible and be able to accomplish what I am trying to accomplish.

Using a 660 ballast already? Make sure its a 09 serial number ballast.
If so wire up 2 T5's with 2 VHO actinics on the Ice Cap (yes you can run both types on the same ballast) and grab a 2 lamp T5 setup. With 6 lamps you can grow anything in the 75.
