i would suggest gathering at least five extra sabers. they dont have to be expensive, just strong enough to spar with.
Ive also noticed new people into dueling aren't exactly thrilled about getting hit during the learning process. gloves and protective gear are great to have around just in case. i always get bruised knuckles somehow, so i use motorcycle gloves when i duel, and it makes a huge difference.
i also made a "cortosis shield" out of a couple of shin guards to wear on the forearm. and that also helps with confidence during practice, knowing you can bat the blade away if you hesitate.
make a few of these to keep lying around.
find a good place to meet and practice. i usually look for places that are kinda private, it seems there's always someone around to talk some kind of trash, and even though you might not really care, it still kills the fun.
i know north park has a ton of space with hills and stuff to run around, so that shouldn't be hard to do in sd.
come up with a well rounded system for those people with different reasons for swinging sabers. some people need the exercise, some might be doing some kind of choreographed performance, some might just want to battle it out.
if i can think of anything else, ill let you know.....
