Im hearing you loud and clear, i have an almost perfect aircraft, except lack of luggage space. the big jabs really appeal, but if you do want to go into CTA than this presents a huge problem. If the engine issues persist, the best intentions might still prevemt CTA acesss. A rotax in a jab also prevents CTA access.
To me the perfect aircraft is a jab with a rotax, or a jab with a parachute thats allowed into CTA. But the rotax prevents CTA and the parachut chews up useable weight.
A few questions to ask yourself that may help.
What IS your typical pilot and pax weight?
What type of range will you need for what you intend to do?
What luggage will you need?
do you ever want to lease it out?
Do you want visibility in flight or visibily below? I have a low wing, its brilliant in turns and flies and lands like gold, but they get very hot in summer and they are poor for looking at whales or features below you.
Where you can get hangarage, is a low wing or high wing more likely to fit? The opposite of whats in location is more likely to fit.
If CTA doesnt worry you then my choice would be a jab with a chute. Fore high cruise speed, good useable wieght, amazing airframe and huge luggage space that will take light weight toys, eg: snow, bikes etc.,..
