Hi,
I donīt know about the rest of you, but for me, regardless of flying characteristics, a turbine jet has to look like a jet.
Given your flying experience I think that a CARF Joker would be perfect.
The K-85 is the perfect turbine for the plane, and it has a very wide flying range. You could fly at slow or medium speed to get used to it, and then when you get confortable, if you like you can tear the sky with it. In our club there are several of them as first jet plane, and all their owners are very happy.
Regards
Eduardo
