yeah, I have alot of vid clips about the 3 sectional from P2P programs and they are nice...in the American Taekwondo Associationt(ATA)--the one I'm under--they have the 3 section staff as one of the weapons you have to learn, but that's like 3rd, 4th, or 5th degree...I can't remember...but yeah, I don't see much 3 sectional unless it's in wushu or kung fu...
The nice thing is that alot of the Students and Teachers at the ATA World Tournaments use the 3 sectional as their entry...and the same with some smaller tournaments, which is good eye candy, considering you never see it performed on TV, or anything else. Also, at the World Tournament, there are seminars where you can get certified in the 3sectional to teach as well as the kama, sword, or any Pro-tech Weapons System...
