Robert, all 3 planes are very good looking, and I can comment on the flight performance of the 4* and the tiger. both planes are very gentle and esy to handle, but with the high rates on they can also be very aerobatic. A .46 would be great for either the 4* or the tiger.
I fly my tigerII on a .40 and it is a quick plane with great manueverability and can pull a respectable vertical line.

Whichever you go for good luck and keep us posted
