The outer section (approximately 4
pounds (not grams)) of my DWFW was flopping around like a beached whale because the damping material was so worn. That had to create vibrations that were 100x what any LWFW might cause due to out-of-the-box unbalance and its probably been that way for several thousand miles.
Any flywheel that is several grams out of balance won't destroy an engine - or a failing DMFW (with 4 pounds wobbling around on the end of the crankshaft) would be the end of every engine.
I installed a Sachs High Performance Spring Hub Clutch, PN: 88-1861-000-017. Drove it home today, runs and shifts great.
By the way, I skipped replacing the IMS too. If it's gone 90,000 miles, I figure that there is no reason why it won't keep working. Call me an idiot if you'd like, but I'm spending the IMS replacement money on new tires and more track time.
