Yeah I think you would have been better skipping the red and using two NWs in the center and 4 CWs around the outside with the RBs, if you know what I mean. If you later felt you needed it you could add lower wattage reds and greens for affect. I'm thinking the two 3W reds will too much given they'll be running at the same level as the RBs but may be OK too, guess we'll see
