Ended up not going last week..my wife and I were both feeling unusually tired, and I had a headache, so we decided to stay home for a couple days rather than go out.
Just got back from the first class about an hour ago. Was tai chi first, followed by shaolin. Per the instructor, they do it that way to try to encourage people to attend the tai chi as he believes that you need to train an internal art if you're going to be doing an external art.
The tai chi was cool. Definitely different than what I'm used to, we went over very basic application but it was mostly just practicing the first few moves and form correcting. Once a month they do a seminar instead of normal class where they delve into application (this month it's next tuesday and will be focusing on sweeps and defending takedowns with taichi movements).
He said that it's not yang 24, it's a different 24 that takes the yang one and combines chen and wu movements. I didn't ask him why - I don't want to sound like I'm doubting their system on the first day, and it'd go over my head anyway.
The shaolin was surprisingly similar to my original style...which was shaolin kempo, except the head instructor also learned an animal style and added that in...maybe I shouldn't have been surprised. 10x easier to me than the tai chi.
All in all, I enjoyed it, and plan to sign up/continue going.
