I train a form called 'Fith son's double ended cudgel' or Ng Long Gwun. It is the first weapon trained in our school - after that broadsword, spear, straight sword and then elective weapons.
It is a northern-style staff set and uses a flexible staff (rattan) about head-height. The hands are held the same way on the staff (ie: both palms down) - apparently because monks/villagers were used to carrying water-buckets on a pole this way (across the shoulders). The staff strikes follow the body closely to generate power and create a whipping strike - feels a lot more 'alive' than hardwood. There are several kicks, traps etc. in the form, which is quite long, but can be broken down into two sets.
Chinese staff forms are often related to spear sets, and tend to grip the staff near to one end when striking, as opposed to holding the staff in 3rds.
We also do padded-weapons sparring (with helmet, arm/leg guards, chest pad, etc.) and the staff tends to be the easiest weapon to free-spar with for a beginner. It's interesting how the target-focus shifts to the extremities - wrists, ankles, top of head...totally different than empty-hand sparring. I have tried sparring against a staff with a katana, but it's very difficult. One of the drawbacks of padded-weapon sparring is that you can't deliver a straight thrust (no 'poking' strikes) as it's too dangerous. Takes away a fair amount of techniques - esp. with a sword... lots of fun though.
