Unless you are naturally very ambidextrous, you may not have much success as an adult learning a 2 hander.
It depends on how much time you have to practice. It also depends what level you hope to be playing in the future. In my opinion a one hander is like a classic car. It is really cool, but maintaining it will become a second hobby.
I switched to a two hander, took me a while to get it too, but now it's my rock. I mean SOLID, and not just for defending. It will never have to pace and spin of my forehand, but it never leaks errors either; and I can redirect serve returns with topspin. A distant fantasy with my old one hander.
I change my signature too much
