Dura Ace, EAI, or I like the Andel ones from Velo Solo too.

Basically stay with steel, avoid aluminium.

I should have taken a photo from a better angle, the chips are at 45 deg to the edge of the sprocket. Means about 1/5 of the width of the tooth is gone. Definitely like cheese though, you can see the porosity in the steel it's that full of holes.
Anything worth trying in terms of cost/quality between £7 for Miche and £45 for Phil in 18T?
