I recently asked a LFS rep there opinion on the pro setup. There reply was that it was a nice system but it does have one major fault.
The housing in which the MH's are kept in have very poor ventilation, this is running the bulbs much hotter than they were intended for. After just a short time on the market, people are returning these units due to increased yellowing of the bulbs, which is most likely from the high heat exposure.
It's too bad that Coralife didn't study this design a little more
