Ahh, the old days, when sex was safe and skydiving was dangerous, haha. I made my first 50 or so jumps on that type of gear. Those springs had a habit getting loose, dislodged, or popping out. They needed to be replaced, though. I remember the pin fix, not sure if it was legal but it worked. Just think, though, half of your jumps the reserve was marginally workable? That's black death, brother. Ha!
Double Ha!, yer older than me! (Grinning cheshire-ly)
