Anyone have any solid data on the effects/dangers of a lightweight crank pulley? There are so many articles going in both directions. Going from a 6 1/2 lb pulley to a 9 oz is so tempting but not at the expense of the bearings, crank, oil pump etc...

This article from Steve Dinan has been around for a while and I know Larry at Endyn only uses Fluidamper (not available on my D16).
