MH 14k/20k With Highest PAR Outputs?

[rastaangel]

Up until now I have run 10k bulbs in my fixtures... it has resulted in amazing growth but the colors arnt as nice as before and its time to buy new bulbs. I will be going with either a 14k or 20k bulb for some nice colors but I want high as possible par for good growth...
Which would be the best bulb choices?

look up Sanjay's lighting guides. They're on several sites. He lists a lot of great bulb/ballast combos for color/par.
Personally, I like Radium, Ushio, Reeflux and Pheonix. XM's are great for growth, but their color is terrible.
