One large skimmer or 2 medium skimmers?

Having said that I've run across a few amazing large tank builds over at RC running 2 although if I recall correctly they were both high-end skimmers each already rated to handle the user's load.

I'm running 2 skimmers on my system, I had wondered if they would limit each other but so far they don't seem to be and both work fairly well.

The reason I ended up with two is that I had a pump fail on my SWC 250 cone skimmer and I couldn't afford a new skimmer rated for over 700g. So I got a Skimz SM252 skimmer, to run in the mean time, and then eventually I replaced the SWC pump and now I'm running both.
