The Trois Etoiles were the stylish spokes (basically the only SS spokes back then), the the Sports were better spokes. Both suffered from inconsistancies that were a curse. Both lengths and depths of threading varied. (Diameters were inconsistent too.) The current practice of lacing on every nipple exactly say two turns to start a build, then observing a nice true wheel that just needed a lot more turns and tweaking as you went - nah! Thie Robergel spokes, you spent a half hour just juggling nipples to get as remotely true and round wheel.

The Trois Etoiles were famous for getting tired and breaking. The Sports made wheels that lasted a long time, but there were always 2 or 3 spokes per box that just broke.

Sorry to shatter illusions here, but that just is what is. I raced in those days, riding big miles and nearly all of them on Robergel Sports. Had one set of Trois Etoiles. Beautiful looking but not up to the job of being one of my wheels. Building my first wheel in the '80s with Wheelsmith spokes was a revelation. "This is easy! I had no idea!"

Now there isa one good use for those spokes. As a task for Sysaphus. Instead of pushing that rock, have him buildwheels with those spoke, 4 per day for the rest of his life.
