My Rancilio Rocky is due for replacement burrs. After reading about the Ditting burrs in the Vario, I'm curious if there is a better alternative to OEM replacement burrs?

Disclaimer: I grind for brewed coffee only, so please no "replace it with an HG One" comments.

Rama,
I'm in the same boat as you with the Rocky. I'm very intrigued by the Vario + Ditting metal burrs as well. I replaced the burrs on my Rocky about a year and a half ago and did the teflon tape mod, which helped from an espresso grinding perspective. I'm 99.9% brewed coffee anyways, so at this point espresso grinding is of little importance to me.
As far as I can tell there are no other options other than the OEM 50mm burrs. My Rocky has pretty much sat unused for the past year + since I picked up a OE Lido. The Lido is a fantastic grinder and grind quality is excellent. Bard & Doug at OE are great to work with and recently upgraded mine with the latest/greatest improvements since I was one of the early adopters.
At any rate, I'm curious if you do find any other burr options for the Rocky. I think I'm ready to put mine of the market, so I can pick up the Vario+Ditting burrs
