They each handle a little diferently on the ground and during that very
short critical time of not quite enough speed to fly but plenty to
ground loop!
I'd opt for the Decathalon for openers, and get time in all of them to
find out for yourself which you prefer. Certainly get the spin
training, invaluable experience no matter what you end up flying.
aerobatics ditto.
Have fun!! where are you flying in SoCal? If anywhere near Santa Paula
I HIGHLY recommend Rich Stowell for primary aerobatics.
Fly safe
