Should I learn the Yang or Chen style Tai Chi next?

I'm no Tai Chi expert, but I believe it's not so much a question of which style is better as which is more suited for you. How old are you and how long have you trained in these arts? The reason I'm asking is because you list so many arts that you have learned, I wonder if you've actually mastered one. Learning forms and Mastering the art are two different things and the real Tai Chi forms like Yang and Chen takes a life time to master. You need to pick which style you feel you are more comfortable with and would like to master. Then it's all just a matter of good instruction and dedicated training.
