Mystery fork, 560g (300mm variant), 75 Euro
Origin8 Pro Pulsion Synergy, 565g, $220ish
Ritchey Carbon Comp 540g, $180ish
Trigon RC38-S, 440g, $250ish

And then there's the Columbus Minimal - 330g, $250ish... but I'll eat your children if you buy the last one before I'm done shopping.

I've sent an email to Easton literally begging them to resume production of the EC90 Aero 1", but I won't be holding my breath...
