I did my twin instrument training on the P68B, and quite liked the plane... Think that it has some excellent single engine performance, it will in fact climb on one engine ( compared to the alternative at my flying school, the Seneca II), and a little less to worry about ( gear down and welded, no turbocharged engines)
Only downside was that it is hard to get in the seats without either sticking your @ss into the face of the other pilot or the opposite.
The instructors at the school off cause knew that, so they would very polite let us, the students, climb in first, and then we got the the full deal of elderly airline captain in our face
But otherwise... I liked it.... the plane that is... not the other thing...
