I've heard good things about the weight and shifting of Stronglight CT2 chainrings, they look better than praxis, especially on a crank like the clavicula.

Came from extralite to praxis. Night and day. Extralite are very finicky and flex. You also have to make sure your chainring bolts aren't too long or they won't tighten down. I had used stronglight in the past and never had an issue with them. Not sure you'll get that much of a difference in weight though.
