I've recently become interested in an art that I've never thought of as martial before. It looks like an interesting way to improve your base and become more sensitive to your opponent. If you're familiar with the art, I'd be interested to get your take. If You're wondering what I'm talking about, here's a link to a video demonstrating technique and one explaining the art.
I always thought Tai Chi was best represented by the following video:
Take it out on the heavy bag,
under good instruction, tai chi chuan will compliment kenpo, with base and sensitivity (as you said)... plus, balance, fluidity, and mobility as well.
after a while, one of the biggest benefits is its way of developing martial intent within calm awareness... kind of the black dot / white dot focus thing. teaches you restraint and patience, not to anticipate or react, within spontaneous situations. teaches you to keep yourself in the here-and-now, first in solo exercises, forms, then in push hands up through sparring (what can be more here-and-now than a fist coming at your head?)
the logical progression of the push hands (which that first youtube video is very good) is from cooperative to non-cooperative. first through uprooting, then locking, and finally with controlled striking. you move from fixed stance, to linear, to circular, to free form mobility as well.
