A friend with ataxia finds she walks best with one pole. With two, she does trip over them and can't use her hands. With one, it provides a bit of stability that she needs. Also, it's a psychological prop, particularly with the yellow and black hazard tape she has wrapped round it; it says "I have a disability, I need a little bit more time to cross the road etc, and no I'm not drunk". You don't have ataxia afaik and might find two or no sticks better than one, but point is, try and see rather than dismissing it out of hand.
