Thanks ned, I guess you are right, it's just becoming familiar with certain equipment is what I was wondering. But I see your point, if you know what could potentially take a good exposure, that theory should work with all regardless what you have.

I currently do not feel like I need to upgrade, especially with my two speedlights and umbrellas and reflectors and so on..but I was at an old Spanish fort last week and they explained their rules...first one was, no flash! So needless to say, this is when I wished for a better camera, one that can handle higher ISO with less noise and so on.

I know I can take most of the noise out with post processing, but in the past I noticed the image with less noise will always come out looking much better over the one with regardless...unless my post editing skills is just not up to par, which can be the case as well. I own both CS5 and Lightroom, both combined I'm sure can make any picture look good...if I can get that down packed, then maybe I won't be itching for an upgrade.

I was wondering also what about a backup?...as many of you seem to have more than one setup..I have only one. I was thinking about a D7000 as my new primary considering it can support all lenses basically and it's low noise with high ISO seems appealing along with its price tag in comparison to let's say a D800 or D3/D4? And use my 3100 as abackup.
