novatac mods-appropriate emitters

[Lolaralph]

I want to mod my novatac 120t, I have a KXK2-PWC4-200 from LEDsupply and a UVOE from Photonfanatic, Im curious as to anyones opinion on which led would work better. If i understand the binning info, the PWC4 has a Vf of 3.65 but the UVOE is much lower, I think. I know the PWC4 is much cooler, this is what i want colorwise, but is the Vf of 3.65 too much for the novatac?

As always, the vast knowledge of CPF is appreciated.
