Thank you all for your help. I am probably overthinking this. I do like some outdoor shots of people with my DL. Nice focus and nice awb/skin tones with the 50-200 lens. I realize I shot at iso 400 and 800 and I liked the look. I was shooting a band in a darker spot so I never changed the iso but still looked good.
I realize that the few times I have done low light it wasn't so great but I think I need a faster autofocus speed for continuous shooting more than anything(not sports just say a kid hopscotching, on a swing or seagulls in flight) I have attempted more of that than low light and I am sure any of the newer cameras will do that for me.
I loved the feel and build of the K7 when I held it and felt right at home with it so while my gut says something like the Kx/Kr if I am going to upgrade, I want to upgrade to a more pro body and vf hence maybe a K7.
Thank you for the comparison info and the suggestion of switching bodies just to try my technique on another camera. My gf liked that idea. But I think I will stick with Pentax.
Oh, here are those outdoor shots. Most straight from the camera with no processing and I am happy with the DL for this kind of stuff.
