Oscar, Murphy was gonna get ya, one way or another.

I've never heard of a problem with the power-links. Personally, I've put lots and lots of miles on a fair number of Sachs/Sedis power-link equipped chains and never experienced a failure. A hyperglide chain that has been broken and re-joined incorrectly will fail quickly.

JonR, what solvent do you use in your park chain? Just today I tried Simple Green for the first time. I'm sold.
