Which camera?
On the k-5IIS I prefer the Adobe profile but on the k-3 I think the embedded one works better.

What do you mean 'most natural' profile? It is a RAW file, there is nothing natural about it. It has to be interpreted before you can even view it. If you mean closest to the jpg remember the camera processed the RAW to get the jpg and did so using the jpg profile set in the camera.
Also, curious why you are converting to DNG? Most Pentax cameras allow you to shoot in DNG which saves a step.
