That’s a cool project and a gr at idea you have there, draddog. I too would would the Nrrodguard since it has the second handle that sticks out making it more “cane like”
Yeah, my physical therapists like it the best because it's more ergonomic. I also realized that it has two covertec holes (one on each side), which means that I can have a wheel on each side. That will give me something better to grip onto.
