The only place I use Quick-Pins is for my hotstick (and I always take it off when I hit the beach), and for my mainsail clew to boom attachment. I like to drop the boom when on the beach !!!
In my first month owning my TheMightyHobie18, I lost my quick-pin on my boom / mainsail clewplate... it was at the worst time possible (high winds in a jibe) and almost lost the boat to a sea wall that day. Once the sail and boom aren't connected... well that like your wheels and steering wheel seperating on your car. I would suggest using a shackle at that place.
