yes, eai on dura ace is fine, but once you've used one brand, stick to it. differ cog manufacturers all have slightly diff thread tolerances, so by using a variety of cog brands, you may be shifting the threads on your hub, and i've seen a few hubs stripped because of this. go with eai, but then always go with eai.
