They break because you don't know how to install a chain properly and/or abuse your chains.

SRAM provides an answer on the relative mertis of the PC48, PC58 and PC68. In that order, cheaper to expensive.
So in a nutshell you are just repeating your flawed assumption that there is always a direct correlation between MSRP and quality.

If we are going to do a nickel outer link, we would have to change the hole size for the rivets to compensate for the nickel plating. Yes a chain is that precise.

And fixed.
