Not sure if I didn't hit the "submit reply" button or my post got deleted, but I'll try again for posterity.
As I become a more and more experienced skydiver a decade into jumping, I am less and less sympathetic to gear with significant failure modes from perceptibly normal operation or minor faults.
In the case of the Racer dual RSL, it will try to kill you if you follow instructions in the SIM. This is for sure the worst offender I can think of in that category. That simply should not exist in skydiving. The "borrowed gear - borrowed death" age should have been long over by the time I became a skydiver.
I've actually met someone who a Racer almost killed. He bought a rig second hand and downsized into it. He was very heads up, but never in a million years did he think that following something in the SIM would almost kill him. But lo and behold, it did.
Even if you're the most heads up skydiver and know to disconnect one side of the RSL in a high speed mal - someone will buy your gear, and selling something with that RSL to someone else is just reckless.
