Don't cut corners now - you've come this far. You really need to replace that flywheel and the bearing in it. Flywheels are cheap and I would not even consider resurfacing.
He is a professional mechanic, he can decide for himself. He won't make another post tomorrow about why his clutch is chattering.
I am quite aware of that and respect him. I am also a pro for the record. You?
Master here .
If the flywheel isn't worn and it works well, Why would you replace it?

NO chattering - just bad bearings.
Now PP and clutch are a consideration. But again if no abnormal wear with long service ahead.
