Duck, wondering if you are like I was/am? When I was 20, I put everything on the cheapest wheels I could find, most of the time they were 2". I was plenty strong/dumb enough back then I could just push those tiny wheels over most anything on the ground, and it was nothing. Now, old, fat, and infirmed, I won't even look at anything less than a 5" wheel. Money is no object, I want quality easy rolling, and locking. I just want to get down on my knees the one time when I mount them on the tool, cabinet, storage bin, whatever they are going on, the rest of the time a flick of the toe, and I'm off to the races. :-)
