I did this job myself a few years ago. It was easy and well worth doing ... a good winter project. I bought all the hardware and rented the heavy duty grommet setter from Sail-Rite. They were very good to work with and gave great information. One caveat -- when you lay out the locations of the grommets, make sure that you don't put one where the sail track "gate" is located. Check this for both the normal full-hoist position and for the reefed position. I made that error/oversight when I did it for Mondial. When the main is reefed, one of the slugs is at the gate and the outhaul tension bent the gate. The easy way to account for this is to measure the distance from the tack hook to the gate and then make sure that on the sail you don't put any grommets that distance from either the tack cringle or the reef cringle.
