As long as "anything goes" you will find it hard to make a choice that suits YOU. You have to find out what will suit you, considering:
- purchase budget
- operating budget
- operating performance demands (touring)
- operating performance demands (aerobatics)
- insurance considerations
- average hours per year flown (touring)
- average hours per year flown (aerobatics)
Make a list of the things and aircraft can have or do, and to which degree you find each property important, by giving each item a value number.
For instance, long-range capability, more than two seats, luggage volume, speed, short field capability, etc.
Have a look at many aircraft for sale (PlaneCheck, Trade-A-Plane, GA Market, magazines, notice boards, etc.)
Grade each offer against your list. Add up the values.
The total gives you an idea how well the aircraft answers to your wishes.
You may have to refine your list a few times as things crop up you haven't thought about before. Re-evaluate old results accordingly.
After a time of making consequent evaluations, you get a prety good idea which aircraft type is the best for you. And you will have made your discovery in a dispassionate way, without being lured into wanting things that don't matter very much.
It may lead you to types you haven't thought about before and surprising conclusions.
You say you want an aircraft you can use for touring as well as areobatics. Would you be spending more time touring or more doing aerobatics? What kind of aerobatics? Are you planning to enter competitions, or do you just want to be able to loop and roll and fly upside down?
