The stick is available in two versions: Wushu and Southern. The Wushu version has thinner ends to allow it to turn faster, so the staff’s weight is more in the center as it is turned. The Southern version has thicker ends and is more of the classic stick for traditional kung fu. The southern staff behaves naturally and is not optimized. The difference between men’s and women’s versions is minor, but the women are slightly slimmer and have less weight.
For Wudang Kung Fu forms, I recommend the southern staff in your individual height. If you are over 180cm tall, go with the 180cm version – it will still be comfortable. Master Ziji is 198cm tall and is using the 180cm version too.
