The above is for top end .21 Nova engines.

Any other pros or cons?

Reason I ask is that a 14.5mm Nova steel bearing is $25 cheaper than ceramic and to be honest I dont thing the standard ceramics dont last long.

I thought about TKO but I hate the way the balls face the front of the engine because the off set inner race is on the other side.
