Which twin turbo-prop?
Congratulations on the upgrade!
Somebody may be able to offer some real good advice if they knew which plane you'll be flying.
My only PT6 experience is in the Cessna Caravan. I imagine every installation is a little different.
Though I only flew the Caravan for 350 hours I have a very favorable impression of the PT6. It's easy to start (as long as it's not too cold [<-30C]), easy to manage (but will "spool down" when idling too long), and almost bullet-proof.
Also it's fairly easy to over-torque on takeoff if you're not paying attention. Maybe you've been flying turbocharged piston twins with an automatic wastegate. Setting power on the PT6 will take some attention.
I hope you get some better feedback.
Good luck.
