Goodafternoon:
I agree they can only do so much and whatever you teach it must be direct and to the point. Getting out of the way and inflicting immediate pain to their attacker.
Luckily, Kaju was not made for the muscle bound but for the smart bound. I think we have plenty to offer.
The cane is great but my dad doesn't carry one. He does however have a great left hook.

My mom has a great arm she can throw just about anything from slippers to whatever is in reach and nail someone with it.

Trust me I know many years of experience.
So, I guess the best answer that I can relate to thus far is yours Sifu Al.
Sifu Al, if you have time maybe you'd like to get together. I like your way of thinking. Maybe we can run through some techniques/ideas. I would be greatful.
Thank you to everyone that posted. I appreciate it.
Soifua,
