Are the Falcons your only choice or are you evaluating other aircraft as well? The reason is that you also need to consider reliability and down-route servicing centres should the aircraft go tech. I'm not going to put one manufacturer above another, but you might want to ask people for an honest opinion of, for example, the 7X's despatch reliability as it's still a relatively "new" type on the long-range block.
Hope it all works out.
P.S. if you want a G450/550 driver, PM me.
