I had the clutch and flywheel replaced on my Octavia TDI 6 months ago. I was advised to go for the solid flywheel conversion, which I did, and I am pleased to say I couldn't be happier.
It's much smoother, quieter, and free of rattles and much lighter on the clutch pedal now than it ever has been.
I wouldn't hesitate to try to point you in this direction!
The kit that went into mine was a 4 piece Valeo kit, cost me £300 for the parts, and £120 for fitting. Compare that with £1100 from Skoda, and there wasn't really any competition.
I have a mate who is a taxi driver in the Scottish Borders, and he has now done over 100k miles on taxi work with his solid flywheel conversion without any problems whatsoever.
