Choosing your weapons

I am getting together with my instructor and picking out a weapon to learn. I sent him a list of the weapons I currently own, that I'd be interested in. Ultimately, I think I'd like to learn the Bo, but mainly because I have two of them and I'm short...It gives me a reach on an opponent. I may not get that as a weapon of choice, but I've told him what I have at my disposal.
I also have a pair of (cheap) kamas, a pair of wooden tonfas and a pair of wooden kamas. I don't own a pair of sai (YET!), but that's also something that would be interesting to learn. Then there's the idea that a cane is also a weapon, along with the fan and other things....

As I was doing research, I found an interesting article by Scott Shaw about the Korean Long Staff. I'm interested in it and have a strong leaning toward either the bo or Haidong Gumdo (Korean sword). I should see if my brother would be interested in talking to MG about HG.
