A friend claims he found some at his local hardware store, that are identical to the DTs that QBP used to sell.

Spokes have larger radii now to better fit modern alloy hubs. So, don't work so well on the old SAs. It's not a matter of the flange cutting the spoke, but the unsupported bend flexing to fatigue.

I use 1 washer on the outer spokes and 2 on the inners when using DT spokes on SA hubs.

2 on the outer and 3 on the inner with Wheelsmith spokes.

No trouble so far.
