Using a single weak link is a bad idea because the lifetime of a weak link
under load is limited (i.e. after x launches it has a good chance to fail
under much less than the nominal rupture load).

Hi All,

Our commercial operation (more like a club) is starting to do winch
launches. I just bought a Tost weak link for my glider from W&W. Are
most people using a "single" weak link or a "single and a reserve"
weak link? Thanks.
