1: don't save on equipment and buy the good stuff
2: always have a backup system (chain, etc) for when the good stuff fails
anyway
3: when somebody tells you otherwise, always remember 1 and 2

Two examples spring to mind where 1 & 2 were not adhered to. The first
destroyed two gliders, seriously damaged three others and effectively put
the club out of action for 3 months when a glider fell from the ceiling
when the hoist failed (poor quality cable brake) and there was no back up.
The second seriously damaged three gliders and injured two club members
when a glider fell from the ceiling when poor quality steel cable snapped
and there was no backup. Seperate airfields.
