Hello

I have a question about the engines mentioned in the title.
I have the possibility to purchase the T10RC, T10 and the flash for a very good price, every one at about 240 euros.
Now my question is, which would you chose?
I'm racing on tight technical tracks, but also one big track (Lostallo).

What I have seen is, that no one of the RB engines are having ceramic bearings, whereas the Nova Flash do have ceramic bearing.
I think, that an engine in this price range should have a ceramic bearing.

I'm driving a G4RS 09 and i plan to run this year with a new engine.
Also important for me is, the engine should be easy to tune.

Can you give me a help in this matter?

Thank you and kind regards from Switzerland.
