I am wary of hand-swage lifeline fittings. For example Rigging Only refuse to sell them. You just do not get the security of a machine-swage fitting nor the near-guarantee (as much as anything can be guaranteed) that the connections are good enough. I used to do machine-swage for people at a boatyard where I worked and you never saw anything so secure in your life as a well-done machine swage. It's what most of our rigging is held up with.
I won't comment on Suncor or Sta-Lok or similar fittings; they are not 'hand swage' and can be done very reliably by following directions. A proper set of either would make good emergency-repair kits on board. I just would avoid the hand-operated crimping tool and the fittings used with it that a lot of people go to when they believe machine swage is impractical, less reliable or expensive. Of all things, with lifelines, I wouldn't try to cut corners.
I'm having all mine redone with 5/32" 1 x19 rigging cable having NO outer core of white vinyl, which is essentially ocean-racing spec these days. And the same guy who's doing my standing rigging is doing those, and for the same reason.
