Flywheel: resurface or replace

Being an engineer-machinist, I made a fixture for my lathe and faced off 8 thou with a nice sharp carbide tipped tool. This method is often frowned upon in favour of grinding. But I have to say my new clutch is as smooth as a very smooth thing!! And a new OEM flywheel here in the UK is £600!
Did you measure the surface finish afterwards and if so, what was it?

I think you should take the time to replace it with a lighter one 
Since its already out you might as well go for it. If there are heat spots on the old flywheel it won't ever be as good as a "brand new" one

If you'r interested, i have a science of speed lightweight flywheel that needs to be resurfaced that id sell for $220 shipping included, youll have a brand new lightweight flywheel for about $75 less than what a new one without shipping would cost, but like i said it needs to be resurfaced

No I didn't measure surface finish with a machine, however it was fine. I was more concerned by flatness (due to the hard spots), and the runout between this face and the back face that bolts to the crank.

Thanks for the advice, everyone.
I heard lots of good arguments either way.. So I thought that if the shop was confident in resurfacing I'd go that route. BUT, the next day they changed their reco because they saw some additional pitting. (Caused by a broken fork.) So, I went the Honda OE route for the full kit. About $150 additional.

wait until you first push in that new ap2 pp, your leg will go through the firewall, lol. All pp's from Honda are now ap2 designs, perfectly fine, but they are so much lighter than ap1's. I just put in an ap2 pp, oem disc and act ultralight flywheel (8.6 lbs ?). Feels really good to me.

Did you end up doing the clutch yet? I just learned in school that a shim should go between the flywheel and the crank if resurfacing so that the distance between the pp and the TO bearing. I couldn't imagine it would make too much of a difference though. Let me know how it feels when it's done.
