I have an Izumi "Super Toughness" chain on my Pake and I decided to ditch the masterlink. I was wondering if it was safe to keep breaking the chain via chain tool every time I wanted to clean it, if so should I keep pressing out the same pin or move to a different one each time? I called the LBS and they said to stick with a masterlink because every time you break a chain it weakens the pins and leads to failure. Is this true?

Also, could I run this KMC masterlink on my Izumi track chain without any issues? I realize it's obviously going to be the weakest link in the chain due to quality differences, but does anyone here think it'll be an issue down the road?
