adjustment for soft tracks

I have never received the same kick response on new, soft snow as on
hard track. I would like to hear suggestions as to what adjustments
should be made for this condition:
- wax: use a considerably softer wax and cover it with the wax for the
temperature?
- ski: use a softer pair of ski?
- technique: ??? right now I feel I am wasting a lot of energy
pressing the ski down without getting the response
- expectation: may be I should not expect the same kick response as on
hard tracks period?
