Lear Dude, I went through training at ATL for the 350 back about a year and a half ago. I had about 50 hours as SIC in the aircraft prior to training and was the only one in the class! Did every sim session solo as well as the checkride. Trust me, if you have 700 hours in the 200 it will be a breeze, I had no problems. All the instructors there were very knowledgeable and fun to work with. Please PM me as I have some training material that you will likely find useful as well as tips as to where to eat/stay while you are there.
