Riding trikes or upwrong ones at the least is a learning experience, you need to forget everything you know about 2 wheels and start all over.
Recumbents offer a better experience, but you do need good access to store one.
I am biased, I prefer 'tadpole' designs over & 'delta' ones, for the sole reason I haven't ridden one !
I am not speaking from experience here , but if you want a tilting trike, the 'delta' design might be best, but I think to benefit from a tilting design , you need to have speed to maintain equilibrium, otherwise your getting back to the balancing thing again.
Totally understand unrelated , I row for pleasure, the slim narrow hulls seen in competitive rowing also need to be balanced, it's the same principal , forward motion makes them stable.
I think for you, a Delta trike might be best, the Hase and Kettwiesel companies are popular for the continent, , and are perhaps easier to get a ride of one over here.
Kevin Dunsheath of D.tek comes to mind, or Mr.Magoo on this parish, or you might try London Recumbents in Dulwich, South London, there are others, but THE place to try is the Netherlands, many companies over there , plus a wonderful cycle environment.
