Please post more details! I have this same CF CS cane, and I do love it, but the aluminum "golf" ball is a bit too small for my hands to be comfortable. I would love to follow suit. Even a billiard ball would be cool, since I use it as a walking aid, and not a self-defense tool. I do like the round form-factor, as opposed to the "hook" style tops on most canes. Please tell us how you did it, or if you're selling compatible ball heads for it. Thanks. (Really nice pics, btw - how do you like your Samsung Galaxy Note II? I'm a new Galaxy user, just got one yesterday and I'm loving it!)
