Well, I have been thinking about getting a pair of these. Mainly because some of the other students and teachers at my school practice with them, so I would love to learn.

Could you guys and gals explain to me the different types of wood? Which type do you prefer, why?

Sizing (if it matters, I don't know) Do they all come round in shape or are there octagon shaped kinds?

Anything else you can inform me about these would be really cool.

May the force be with you.
