I've had then ping out with kite sheets... but never bend out of shape.
Fast pins aren't fast without tape! |

I know someone who nearly lost the whole of their rig over the side trying to adjust them on the water. I personally wouldn't bother on the water but they can be advantageous on shore

Put them in from the inside then the ring is protected from kite sheet snagging. I also use a standard pin in the topmost position so the rig is always secure and changing up is simply a matter of pulling the pin (tied on, of course!)

That only works with the 'fireball' slot system. If you have a simple swaged eye or similar on the shroud and the pin fails, (fast or otherwise) the mast falls down. Don't know why more classes don't use the Fireball system - its simple, easy to use and safe as mast can't fall down. |

The Ronstan shroud adjuster has a pin in the top and the channel is restricted at the top so that with the top pin in the shroud cant fall out. This is handy when changing things on the water so you dont lose the shroud but I suspect that if the fast pin broke the load would be so much that the bent bit of metal at the top of the adjuster would unbend and you would lose the rig.

Regarding the extra pin at the top of the adjuster, rather than fast pins:
I've had a shroud fail at the lower splice and had to wonder if it wasn't because I had an extra pin at the top of the adjuster that caused the shroud to bend round it under load.
The shroud pin was in the aft row of holes so that the natural shroud line exited the plate along the aft edge rather than the top, but the extra pin at the top prevented this alignment. It seemed to me that by bending the shroud close to the splice, some strands (on the outside of the bend) were placed under greater load than others, which may have led to the failure. Otherwise the splice looked good, with the ends of the strands projecting from the ferrule:  |

That's interesting to share.
It seems as though something added as a safety feature could have actually ended up causing a failure. What was the damage when the rigging failed? Just a suggestion, at the dinghy ex. I noticed a Scorpion with adjustable rig (string/wire) there was a wire safety strop though the shroud eye/U bolt in case of failure. Whether you use fast pins, or clevis pins, maybe some sort of soft secondary safety leash would be better to save the rig rather than a 'safety' top pin which could deflect the shroud under load at or around its weakest point where it is swaged.

That isn't the Rhonstan adjuster refered to earlier, and thats probably why it failed, the Rhonstan adjuster has the top pin offset to avoid that abrasion and keep the shrouds inline.
