In dreamland, just one aeroplane is impossible! The only thing that comes close to doing it all for me is the new Yak-52TW - full western spec, increased performance, prettier looks, faster, longer range, taildragger, far more aerobatic than I'm ever likely to be, etc. But it costs a fair packet - you could buy quite a nice used Yak-52 trike _and_ a Yak-50 for the same money. Dilemmas, eh!
In a more real world where I am most unlikely to win the lottery, what I most often see myself in is a Vans RV-8 on a nearby farm strip (it's similar to the RV-4 but more a full two ater than a "1+1"). If I could get a share in a nearby based TB-10 or Trinidad GT for family touring as well, I think the combination would do everything I'm ever likely to want.
