Well, I would probably trade any unnecessary duds for a crate of steel washers, since I used up my supply this year. Let’s take a look:
On many of the 2013 loaners I welded a large washer onto the kickstand -- a “foot”. I just happened to have these and put them to good use. The feedback was unanimous; the washer helps keep the bike upright. This washer is 2 ½ “ diameter. A bit larger would be even better, and likewise if it is a disc with no hole, I suppose.
There are three things you need to watch for: The rider’s heel must not hit the outside of the washer, and the wheel-spokes must not hit the inside. And the washer should not be terribly heavy, lest the stand descend on its own – depending on the strength of the spring.
Some kickstands are aluminum, and for those you would need a TIG welder. Or fabricate a mounting ear or clamp on the washer and bolt/screw/clamp it to the stand.
By the way, this type kick-stand tends to stick (a stick-stand, yes). Squirt a dash of spray lube -- or even WD-40 -- on it, and you will experience a miracle.
Oh.... About sartorial stuff, I'll have you know, as of this year I have a marching band uniform jacket, sort'a Sargent Pepper style, which I laced with EL wire. I planned to wear it to the Meet-n-Greet. But then every evening was so nice and mild, the jacket was too hot to wear! It needs EL wire on the back also, and then I can hope for a cool evening next year.
