IMO B3 all the way. It is an excellent hot and high machine. You can get a hoist, and there are many EMS stc's and mods for this a/c
2.5 hrs is a long way on a tank of gas though. At high power settings you can easily see 200Liter per hr fuel consumption.
the 119.. I dont have any experience, but talking to drivers, <7000 and 20c its great. Hot and high performance goes rather fast. My impression is the charts support this.
what about a 109 Grand?
Good luck on finding a B3 or a 119
