RE Suzuki

I'm changing my clutch and I happen to have the brand new flywheel and a used bonez aluminum flywheel. I have had the bonez aluminum flywheel since Apr. of 1998. I've probably put on 80,000miles on the flywheel. I really don't know how long the flywheel should last, so if you guy could give me some ideas it'll get great.

So heres my question. Should I go for the brand new stock flywheel or just keep on using the bonez aluminum flywheel with 80,000miles on it?

by the way, the bonez flywheel haven't been resurfaced since the first set of clutch.

thankx
