Maybe what I meant was that you have to adjust your technique to get the same
volume on cow as on goat. But you don't really have to change it at all if you don't want - if you're getting a nice sound on goat, you'll get a nice sound from cow skin also. As always, I reserve the right to contradict myself at any time

I tried a kip on my new (since Nov.) DSD drum. It lasted about 3 months, which is relatively very short. Usually a goat skin will last me at least 6 months, while a cow skin can last anywhere from 1-3 years. After about a month of heading up the kip skin, it developed a small tear around the outside of the bottom ring. It was a little suspect, since I hadn't even shaven that area of the skin. It just weakened and tore. Fortunately, the skin still held out for another couple of months, but it wasn't worth the $48. It also never really got that "played-in" sound, which is when a skin reaches its peak performance IMO. I ordered a regular pre-shaved cow skin round from DSD... they're asking I think $35 for them now. They sent me a nice medium-thin round - very even thickness all around. Hopefully it will last longer. In the meantime, I've put a goat on that drum... looking forward to hearing what it sounds like.
My other reservation about using calf skin is that it is very unsustainable. I really wish my deer skin would have worked out better. Maybe I'll keep trying.
