The single mass Dai has sent a link to is about 9kg lighter than the original solid flywheel and is designed to work with the 850R clutch to hold big power so it has a massive advantage over the DMF.
I thought I would do some more research about this specifically revolving around the m90 gearbox. I have found that some people get a rattle in neutral with the clutch not pressed due to the gearbox design. One person said they didn't get this with the ttv flywheel fitted, they fitted one to another 940 and they got it. If you are going for more than 200hp it seems the DMF can't cope and starts to rattle.
