i feel kung fu gave me a great foundation. no matter what other martial art (judo, gjj, hapkido, fma, jeet kune do, etc) i studied afterwards, my instructors were always impressed with how fast i caught on.
thing about training, westerners seem big on categorizing things. there's talk about different combat ranges - striking, kicking, trapping, clinching, grappling. when i learn kung fu, these things were never neatly separated, but integrated synergistically. for example a block could be an attack that could push/pull the opponent off-balance for a takedown/throw.
