What is it about regular bikes that you don't like? And what is it about 2 wheels that makes you think a trike would be better?
Browsing this and other forums in depth will give you some idea of the pros and cons of the different styles of recumbents, and 3 wheels vs 2. As someone who rides both DF and recumbent, I would say to take things with a grain of salt. You still have to pedal all of them. Also, people who prefer DF tend not to spend a lot of time explaining why they don't like bents, while the bent riders go on at length about their problems with DF's. I don't have a trike, but one of my friends who was no longer able to ride his DF for physical reasons got a trike. After the new wore off, he got a two wheel SWB because he wanted to be faster and liked the feel of cornering on two wheels better.
Also, if you are planning on losing another 50 (or more) pounds, you may find that what is comfortable may change dramatically!
