I don't know if this topic has been discussed here before, and if so, my apologies...

Lately I've been trying to compare the style I'm currently learning (Southern Shaolin Tiger Style) with other kung fu styles who come a more or less direct line from the Shaolin Temple(s).

Seems that we have a higher number of stances and some of them even seem different, even though they re supposed to have the same origin.

For example, I saw in the article reposted at http://www.shaolinwolf.com/morechitr...r/stances1.htm
some of the stance work taught at the USA Shaolin Temple.

By comparison, in our bow & arrow and tiger crouching stances, the front foot is curved inside, not straight out, and the front knee is bent so that the toes are "covered" by the knee to protect the foot. (the same principle applies to the horse stance, ie feet parallel and forward, not angled outwards)

Are there other styles out there that have these kinds of differences?
