I think that I've flown just about every left /right / centre / yoke / stick combination going and found most of the transitions reasonably easy. So, I have a few semi informed opinions...
- For aerobatics I'd much rather have a right hand stick.
- For touring I'll take whatever allows me the most room on and around my knees. Touring with a sidestick can be very enjoyable.
- I agree that going from yoke to stick seems slightly easier than the other way around.
- With a single stick between the seats, I'd much prefer it to be 'Y' shaped.
- With a mechanical sidestick I'd like to be able to see the ailerons, primarily to ensure visually that they're parallel for takeoff.
