Who makes the strongest/toughest pinions?

[fastbaja5b]

I found for 5mm shaft the HPI Flux pinion was very soft and wore fast
The Kershaw Designs pinions fit well, but were quite noisy as are the Novak Pinions
My one try with RCM pinions was on a Turnigy 36-56-2600 motor in an E-Savage, the pinion simply wouldn't fit on the 5mm shaft.

I am running the Robinson Racing pinions now on the Savage Flux, works well, and quieter than the stocker.

For the Slash I like the Losi 48 pitch pinions but I change out the grub screw as the ones they come with are rubbish.
