Yes, I saw that from your earlier post, but it's not something I agree with. I've never had any trouble with stainless steel spokes and neither have any of my friends in the trade to my knowledge.
You saw my earlier illustrations of an extremely dished wheel and my use of stainless spokes, and the extreme applications they are subjected to, far tougher than anything you are doing with the UM. In the 700c wheel bike the motor wheel has a narrow tyre run at 80 lbs pressure, so again a high stress situation. That was a Torq wheel, and they gave spoke breakage troubles for some users, but the good rebuild solved that as it usually has when 50cycles rebuilt those wheels for their customers.
Frank may have an alternative suggestion, but I can't suggest anything better.

My Torq suffered breaks at the rim and following a rebuild by 50c it has been rock solid dispite my considerable weight perched upon it!!!
