I like the current dual daylight and dual actinic, only problem is who knows how much longer PC bulbs will be produced, coralife and current I believe have discontinued all their PC fixtures, so may be only matter of time before the bulbs are done too. Lastly power compacts only hold their color for about 3-5 months, after that they get pretty yellow.
You may want ro consider putting the $ you were going to spend on bulbs towards a newer technology that will be around for awhile such as T5, or even LED or a hybrid.
Hope this helps.
