. . . and don't forget, if you have troubles with clipless pedals, you will NOT fall over.

I hear fast curvy downhills are a gas on a trike, too.

I second what others have advised. Give it a chance, put a flag on it if you're worried about visibility (but ride as if you're invisible, anyway), and spend some time on BROL. There is a large and enthusiastic bunch of trike riders over there, they can answer any questions you may have - and if you really decide you don't like it, that's a good place to sell a trike.

I haven't tried a trike, BTW, 'cause I don't need another pedal-powered vehicle - yet.
