Spoon, thats a great idea. I do not have any of the aforementioned problems but will probably give that a shot just for endurance. Good write up...again. You know.....I'm sure something similar is made...but like Pappy said about the little rubber ends...if you molded a little rubber end with a slot and cover that would hold varying sizes of wheel weights...and could be changed easily and quickly...you could probably market that.
"But if serving the Lord seems undesirable to you, then choose for yourselves this day whom you will serve, whether the gods your ancestors served beyond the Euphrates, or the gods of the Amorites, in whose land you are living. But as for me and my household, we will serve the Lord.” Joshua 25:15
