IMO, Tai chi should always both crane and snake at the same time. Smaller and straighter movements are snake movements. Larger, bolder and more stretched movements are crane movements. How they blend into each other should correspond with kai/he changes. Other animals or names, including tiger movements are either crane or snake movements. All movements in the forma are either yin movements (snake) or yang movements (crane). Therefore it's very strange to separate forms or methods into one animal symbol. In tai chi, everything is both yin and yang, blending into each other.
I'm not sure I agree with the article either Bao, but I took from it that the snake style had the most Yin/Yang balance, and that it was the most advanced style. At least that much makes sense.
Yet, to your point, I think there is benefit in practicing Tai Chi different ways. I do the Yang Style to practice big, long, structural movements, but I alternate with Chen style to practice coiling and sitting more in between the legs as appose to being mostly on one leg or the other as in Yang Style. I used to think you could blend both of that into the one perfect form, but I don't see the point anymore. Different forms emphasize different things, why not just practice them separately if you have the time?
