moved from nikon f2 to 7D

My last system was purchased in 1972 as a nikon f2 with 4 lenses. It was time to move on. I chose the 7D for the complete system. I bought a refurb 7d body ( and still got the $200 rebate and 2 yr extended warranty) and used minolta lenses ( 24 to 85mm, 50 mm, 100 macro, 100 to 200 4.5 and 80 to 200 2.8 G ); a sigma 14 mm finishes off my glass
(no plastic elements allowed). Every item was purchased for one half list on ebay. All lenses are excellent by anyone's testing. No regrets here. Perhaps because I bought a refurb body with increased QA/ testing, I have a flawless camera. It has been dropped once and jumbled in its backback without mishap. Images are always shot in raw format at maximum resolution. Processing is by rawshooter premium and qimage pro. Yes, there is a learning curve and I still fumble with my options. But with 3 predetermined settings that I have complete control over, I can preempt the moment of need. (ie continuous autofocus, shutter priority,3 frame continuous, iso of 800 is my setting # 1 for sport shots). I find the focus/shutter release to be quite adequate for action shots—maybe 0.1 sec delay that I need to compensate for by sequential frame shooting. Would I like to have 10 megapixels rather than 6? Of course. But that has nothing to do with the quality of the images I take. Will I upgrade? Remember my first sentence?
