I've exclusively used the Shimano HG-73 on my 9-speed mountain bike with a SRAM powerlink. I've now used the same powerlink on three successive HG-73s. I regularly replace my chain when wear is about 1/16" but reuse the same powerlink. I do carry a spare powerlink but it's still new in the pack. I clean my chain regularly and lube it regularly. I've considered trying a different chain but not because I have had any problem with what I'm using. Never had a chain or Powerlink fail on MY bike - only on bikes of others that are not cared for. That's my experience.
