Actually I find it quite interesting. I am very green with respect to the martial arts, but have been training in Remy Presas' Modern Arnis for the last year and a half or so, and have been doing Shuai-Chiao for only about 4 months. Of what I have seen it is a very nice blend between internal and external styles. While most of the basic exercizes we do are movements that emphasize stretching and "centering", my limited experience working with and watching the advanced students tells me that it is more than capable of being external. It teaches tan-tui forms, and our class at least spends quite a lot of time working on an array of punches and kicks along with the more internal throws and chin-na type attacks. I am far from feeling up to competing in the art, but I have seen the more advanced students go at each other, and while some call it "chinese wrestling", I would be more inclined to liken it to playing chess with your balance.
As far as what I, personally, have learned so far, I am pleased. My teacher is very knowledgeable and comes from a very hard-style background (shotokan karate or something of the sort, if my memory serves), which allows him to sprinkle in a bit of ying with the yang. I have noticed a phenominal improvement in my balance, which has helped quite alot with my Arnis, as I am sure you can imagine. The throws I have been exposed to seem very effective, and several of them I could even imagine being usefully adjusted to suit "real-world" type encounters. Lastly, the nature of the art demands that in order to get very far at all beyond the fundamentals, one must become quite adept at taking falls without the luxury of slapping the mat when you hit. The confidence boost that comes to me as a beginning martial artist when I can fly several feet through the air and land without injury is huge.
So if I were to sum up my rambling I would have to say I am very pleased with it. While Arnis is still my art of choice, I think perhaps some day I might be so cocky as to start intermingling the two (Flow drills would become quite something with a smattering of kung-fu thrown in

). But for now I am content to just try and keep my tan-tuis from looking too laughable...
