How many of these do you have on your boat?
I leave my mast up and only trailer when on the road to a regatta.
Therefore, my need is only at the main blocks to the traveler, and at the jib tack. At the jib tack, it is a shackle with a quick pin shown above (and shackle and pin are tethered together)
My jib head uses a standard D-shackle. That could be a quick pin also, but I have not gone that route.
My jib clew is a crappy D-shackle that needs replacement. The blocks do also. This would be a good location for a shackle with a quick pin. My only concern would be that the clew gets worked a fair amount (no more than the main blocks/traveler), and any failure of the pin would result in loss of jib control temporarily. supposedly, the quick pins do have a higher failure rate.
I would not see a problem using a shackle with a quick pin on the forestay if you have to drop your mast at each outing. I would leave ring dings on the shrouds as those should not be removed much.
