No mix up in aircraft types ( B300 / B350 ) above.
A King Air 350 is placarded as a Beech 300.
The original B300 has its own set of books for both the normal and light weight versions.
You cannot compare take off performance for the 200 / 350.
Simply because they operate to a different safety standard as mentioned above.
Because of this the 200 has to be the winner as it only requires take off distance to 50ft.
