I think a plain ol bo is great. don't get me wrong, chucks are my fave, and sais are flashy, but are you gonna find a pair of chucks on the ground when you want to fight. On the other hand, a broomstick, or branch, or something shaped like a bo is likely to be found. Plus, a wide range of styles use the bo staff. Most karate schools for sure. It's like our master says, if you want a weapon, buy a gun, but if you want to better yourself and learn grace and coordination, buy martial arts weapons.
