What is the general consensus , I currently have a D80 , couple of years old with an 18-200 DX Nikon , a 10-24 DX Nikon , a 105 Nikon VR , 70-300 VR , being just an enthusiast with a penchant for lightning photos , landscape and fishing(gamefishing photos eg, jumping marlin) what is everyones opinion on the merits of upgrading to a D300s or going full frame with a D700 , I guess the main thing I am after is the faster FPS and better ISO performance , not too concerned about the 51 poiint AF as I spot focus for all but the Fishing action shots , I was also thinking of selling the 70-300VR and getting a 70-200 2.8.

All advice welcome .
Cheers
Goatch
