these would go great with the 6201's
you dont need alot of flow through the sump. 2500gph would be just fine to the sump. its enough to get the desolved oganics to the skimmer and then on to the sump. if you build a skimmer make sure its big enough to handle all the water comming out of the overflow box. that way all the water is skimmed all the time. you get the best skimming that way.
energy has about 2500 gph going to his skimmer and his tanks is alot bigger than your tank will be. the key is the size of the skimmer and its ability to skim all that water effeciently. your skimmer should hold between 5-8% of your total system volume. so if you have a 1200g tank and a 300g sump your skimmer would have to hold between 70 to 120 gallons.
the 8 luminarc reflectors will be fine for that tank with 400w bulbs. 400watters are good to 4 ft deep. the 14 k bulbs are a good place to start. they give you the best of both worlds and a fairly good par rating.

Thanks Spazz,
My only thought about having "only" 2500 Gph going to the sump/skimmer is flow in the tank. I know flow is going to be an issue, and I'm trying to get as much as I can. My thought was to have about 4500 Gph going to the sump and another 4500 going to a closed loop. Both returning via there own OM 4 way. I know I can get more flow using less Wattage with Tunze, but I really don't want 8 (bulky looking) Tunze's that have to maintain all over my tank. My thought was to have a nice mix.
My Skimmer is going to be gravity fed form a 2" drain. The water will fall about 15 feet to the skimmer. My plan is to build my own skimmer, but I am also considering just buying a MRC MR-9 it's rated at 2150 Gallons and it's only $1100 it has a 16x12x12 box 8" OD first riser and 3.5" OD second (with 2 injectors).
