all I can attest to is the cx-ray are seriously stong spokes. Expensive but so strong. My wife, not a easy rider, has beat a set for the last 6 odd years on a lightweight set of american classics. I, for the first time in as long as I can remember, check their tension the other day and they were still fantastic. I should note that she also bought them used.
Also the rim is beat to hell, dents all over the place but the run out is minimal as well. They seemingly are worth the dollars especially if your rims last, which I would wager the Edge ones would. Besides with that much money in rims why skimp on the spokes?
