I think you'll want some actinic in there. When I look at my tank (1x 96W actinic and 1x 96W 10k) under just the 10k, it looks too yellow for my taste. The actinic make the colors "pop" and those fluorescent greens really come alive.
You can always just get 2x 10k bulbs and 1x actinic for this light change, and use the 2x 10k bulbs for a while and see if you like it. If you don't, then put the actinic in and save the extra 10k for the next light change.
