Can you take in your old cushions to get them copied?
As for the J2, ours is 140% and is a great sail for shorthanded sailing. You can get a lot of good used ones because the hardcore OD guys on the east coast rarely use them
Because we live in a really windy spot, and our racing at other lighter locations was done doublehanded, one year I stopped carrying a #1 altogether and had the boat rated for only the #2 (playing the PHRF game). The rating was so generous that I felt guilty because we were just as fast in 90% of conditions, but punished the fleet with our handicap.
I am due for a new #2. I just spent 10 days cruising and that is all we used.
