what light to go with

[Mik_101]

Just started up a ten gallon nano reef sytem with 28w PC light soon i will be upgrading to one of these so I can keep SPS a well. The ones I got in mind are. Witch do you think would be better (both these lights sound AWSOME but id like to get some thoughts other than what it says on the website. So far what I have heard from Eugean from Oceanic coral the ICE CooL.E.D sound good but kind of expensive)

-2x O.C ICE CooL.E.D 27W spot lights
or
- Viper HQI Clamp 70W 14K metal halide

As well I would like to know some good ideas on how to incorporate my current coralife 28w PC light with either if these fixtures.

Thanks,
Miki
