I have an HBB on rubber,a DJ and 1950 on leather, and a YM on steel that I wear regularly. I prefer leather over all of them, but steel definitely has its advantages... I would prefer to wear the bracelet to the park for example. Over time the leather molds nicely to my wrist and I prefer that. The strap on my fiddy is 6 years old and I love it
I don't get the rubber strap craze, I really don't care for it. I am currently exploring options for putting a leather band on the HBB.
