I had that problem with my 21SC, as did the previous owner. I did a couple of things, but the one that would probably help you the most is to change out the plastic luff track for the stiffer aluminum ones. Matt probably can't/ won't suggest doing this, I'm sure for liability reasons, and wisely so. I can respect that. I would not suggest that you change all of them either, especially the one that interfaces with the aluminum mast. As he explained to me, doing so would totally negate the purpose of the comp tips electrical contact protection. Fortunately for me, I launch out of my yard and never trailer the boat so my risk with power lines is quite minimal. (If I remember right I only changed out the top two anyway) Your situation may be totally different. Lightening is another matter, but if it strikes that close...I'm not going to be around to write and complain.
Other changes that I made were switching to an extremely low stretch Vectran halyard. I also added a hook and ring system, but have never used them. However, the SC sail area is smaller than the SE, so you will probably need to utilize the hook and ring. Anyway, let me tell you, the changes made beat the hell out of having to flip the boat over on its side in order to pry the sail free because it's stuck and won't lower after a long day of sailing.
If you search the forums you'll find information on changing the luff tracks, there may even be an FAQ. Some suggest that you pry/pop them out with a screwdriver. I didn't want to risk chipping or damaging my comp tip so I drilled out the pop rivets holding the masthead in place, used a heat gun to soften the masthead sealing adhesive, R&R the tracks by sliding them in/out, resealed the masthead joint, and then replaced the pop rivets. If you have the tools. it wasn't that bad of a job. Just make sure that you remove ALL of the rivets. I found some that were 6" or so down the mast that almost killed the job. Should take about an hour if you have all of your tools and parts ready. If not grab a screwdriver, hammer and pray.
BTW, I've also read that others have had a sail loft sew in a plastic slug into the top of the luff.
If the boat is in good shape otherwise, I wouldn't worry to much about the luff track issue.
Good luck to you.
