My Hets will not lock up, the female seems interested, but the male doesn't.

I am debating on putting in my pastel or woma (I have a friend's Woma here breeding right now) in with the female and just holding back a male to try for axanthic combos.

Which would you do?

Het VPI Axanthic x Het VPI Axanthic
Het VPI Axanthic x Pastel
