I use IPACS Aerofly Deluxe and to date I haven't seen a model as difficult to Harrier as my Yak.
Take the Black Extra, crank up the throws, add 20 pounds to the fuse, crank up the sim speed, add some turbulence and cross wind and you will have a snapping/wing rocking machine great for practicing rudder and aileron harrier corrections on the sim.
