I'm driving one of these at the moment, and came from over 2000 hours 206, so I was in the same position as you, except I had a little gazelle time to help with the rotors going the other way. The F1 has the same engines as the jetranger, so there's part of the learning curve out of the way, except you switch the generators on as you start (haven't found out why yet). It's also a noticeably heavier machine and it is twitchy in the hover, but I got it subdued after a while. It comes down like a greased manhole cover with both throttles back, and you don't level the machine in autos - it does that by itself.
I don't know what job you're doing, but ours is an F1 and lifts a 150 gallon water bucket with no problem, plus 40 foot electricity poles. It's pretty good for passengers too.
You will find an excel/Psion spreadsheet for the CG on my website, that gives you weight and balance every half hour
hope that helps
