Primary chain

Andy,

I am running the two simplex IWIS chains you sent me and they work great. Never seem to need adjustment.

Is the merc duplex chain stronger the than two simplex chains or the same strength? Which one do you think is the better chain?

There is not a lot to choose, but technically the Merc duplex is the best as with 2 chains there is a slim chance one chain will take all the load.
