Mr. Hat
I totally disagree that "People straight of pistons will always find it harder"
From my personal experience years of flying a piston, then thrown into a turboprop I loved it, the easiest job I've ever had, ever easier learning & adapting to a multicrew environment then single pilot ifr ops.
The hardest was learning the new company SOP's but after lots of hard work & 50 plus hours of flying I was starting to get my head around it.
My opinion easier. But for a person with the right attitude and skills developed during their time in GA it is very possible for one to go from piston to Jet, I know of many great captains that have taken this road.
Cheers
