OK. Put a notional value on your time, blood, sweat, swearing for the job.

I'm quite sure that I could kill a clutch in a lot less than that if I
was trying...

Personally I think it would be crazy to open the car up to this extent
without replacing this item. However, if you're doing it yourself and
not paying labour, then maybe it makes sense.

Also, if you end up with vibrations by fitting a solid flywheel, would
you be happy with them?

Depends when and how bad - so perhaps. I think I'm going to go with
replacing the DMF though.

I know.

Its a wonder there isn't some sort of electronic detection and warning
re clutch abuse\trauma.

The DMF is exactly about making diesels seem smother. Yes you will
notice extra vibration. As others have said, it depends on whether
you're prepared to accept that.

For me, my car is on 136k and no documented changing of the DMF but then
again, 90k was motorway mileage.
