Is Hsing-I a good intro to Internal arts?

[Judge Pen]

if its so respected why arent any mma or even sanda guys cross training in it. and jang jwing ming's book on bagua actually looks really good, unliek the xingyi book there is sparring in the bagua book.

Isnt' it past your bedtime? Since there's no sparring in the book, then the xing-yi guys obviously can't spar! Go troll somewhere else.
