I have created two new profiles for the D300 & D700 using the Adobe Standard profile as a base. If you don't like the Camera Standard (Nikon NX) look with it's odd Blues and also don't like the Adobe Standard profile with excess Cyan and exposure then this may be the perfect compromise !
You can download them here Nik_Adobe.zip
Copy the files into the following folder and restart Lightroom / ACR
On Mac OS X
