What do you guys use on your yokes? Is there anything that lasts longer
than silicone spray that (a) doesn't stain carpet, (b) doesn't stink to high
heaven, and (c) doesn't leave particulate matter behind?

Another vote for LPS1...spray it on a rag and wipe the shaft with it.
If shaft is really cruddy, wipe it off with a clean rag and repeat.
cruddy...

Less mess and smell than spraying directly onto shaft.

Funny that the first time I had this problem, I wished for LPS1, as I
have used it elsewhere...and what does the instructor grab from the
shop?

LPS1 leaves a non-sticky film. Works great on Piper Traumahawks!
Meets (a), (b) and (c) when applied as above...
