Re: Who uses a Larkshead on their jib sheets?
I've done it plenty of times when one long sheet is used (instead of two short sheets tied with bowlines).
If your clew ring is inset a little bit then it will abrade and eventually damage the sail cloth at the clew of the sail. If the lower and aft section of the clew ring is just metal then you are golden.
The knots can take a lot of work to undo after a year or two of hard sailing. Not a big deal unless you want to move the sheets to a different sail.
My current preference is to use two sheets with an eyesplice at the end of each one and a soft shackle (not a metal one!) attaching the sheet to the sail. The eyesplice plus soft shackle slides around the shrouds cleanly. I have tapered sheets that don't weigh down the clew of the sail as much, and this allows them to be made of material (dyneema) that can be easily spliced, but can't hold knots.
