Lets be practical about this.......
To be frank, you wouldn't get insurance on a TBM850 without an IR and with your number of hours - (in JARLand a Type Rating). You would need to employ a pilot to fly your TBM850 and you could sit in the right seat, but the time wouldn't count unless they were an instructor. In that case you wouldn't need an IR. Why not just charter the plane when you need, and sit in the back drinking Gin and Tonic?
Not surprised you're bored with the PA28 - 161 - it is a boring aeroplane (no offence
) Get something with a bit more power (250HP) , a bit faster (150+ kts) and build your experience. When you have 1000 hrs and an IR then get your TBM850, or VLJ.
