As a 17 stoner myself I'd suggest you forget the 22 unless you've found yourself a lightweight female instructor who wants to have you rubbing your left arm up and down her thighs every time you meet.
The 22 with a couple of big(ish) blokes on board is also not a great learning environment. You're wedged in with almost no wriggle room, an instructor who's nervous 'cos you're always close to MAUW or at the front of the envelope in a machine that was never designed as a basic trainer.
The simplest solution is to learn in a 300. IMHO it's a better trainer anyway and has a spacious cockpit with no seat limit. Other than that, if you plan to get rated on the 44 in the future and use it to fly yourself and friends then there's a good argument to learn on it from day 1.
Best of luck, FB.
