Maybe I am weird on this, been called weird before for other reasons........
For my two jibs, each has its own sheets, granted this costs a bit more, but when you know you will be changing jibs, in my case, 110 to 155 or 155 down to a 110, I setup the new jib's lines in the carrs, on the forestay etc, and drop the one, and hoist the other.
I also admit, my 110 uses a different carr/track that is farther forward than the 155 or my cruising 140 that will be here in a month or so.........BUT even if they used the same carr, I have the carrs that two lines that can run thru, so you set up the one while still using the other, and again, jib changes are kept to minimum time. Even if it is just spouse and I vs when racing with 4-6 crew on board etc.
This method works fine for the hanked on jibs I had, now with a foil, one jib can be up, the other in the lee hoisting, drop the filled on, and new fills almost instantaniously! But again, you need two sets of sheets to do this method, strictly cruisers may not want the extra expense of the lines.
This is my mad or madd or what ever method you want to call it for the use of jibs/geno's etc.
