David,
I had another set of reefing lines put in when I had my sail repaired.
I use the outhaul line as you are speaking, but putting in some reefing lines in is very easy. Just take some line tie knots in both ends so it will stay in the reefing gromets. Then reef early rather than later, if you think you may need it. anything above 15 knots I use the second reefing lines when i get stronger gust and it sails well enough. It also depends on who I am sailing with and their comfort level.
If you look up the Hunter manual it will show the rigging for reefing on the 22.
I have a copy of the manual and it shows the rigging for reefing but it is too big to attach here.
I would be glad to e-mail it if you would like.
