Another advantage is on rolled genoas, the knots make it easier to reach the sheets, when and if needed.
Here Fred, a relatively short person (still), can reach them easily, as can be seen.
As can be seen bellow in this photo, both knots are inside the boat, even with the sail outside.
And I do that with the Spinnakers also.
But with the Spinnakers, I use a thin Dyneema extension line that reduces weight suspended on the sail, and allows me to remove the sheets easily and have both allways attached, but above all reduces friction on forward rotating gybes by less than half once the sheets pass the in front on the genoa tack.
hope this helps,
