I know from reading that people cast feed with Rod's complete reef. I would definitely suggest check out the SPS, LPS keepers forum here to get a better idea. So many variables to this stuff it can be overwhelming if you let it. I am going with 4 Hydra52 and 4 T5 using the Aquatic Life T5HO fixture. Hope it all works out well. Also, T5 has been through it test of time and works as well as MH. LED is the new kid on the block and has growth capabilities as well.
Your lighting is going to depend on the types of corals you want to keep. If you want to keep SPS and have good air circulation to keep the temps down, then I honestly think 9 out of 10 would say MH. If water temps is an issue, then LED and/or T5 should work. Combination even better.
There are plenty of smarter people in the SPS and LPS forums that I mentioned above. All different types of setups with success. So it ultimately comes down to your budget and what you want to keep successfully.
