Good choice Ken. The only thing i'll add is that often it's a good idea just to bite the bullet and have the stick pulled. That way you can pull all the chain plate at the same time and have them duplicated. Oh yeah, since you are going to pull them all, just have new ones made. Don't put the old ones back even if you don't see anything wrong. It's money well spent. It may cost you a little less if you don't take them in one at a time also.
You can use the opportunity to check everything on the mast while it's down. It is easier to do a more thorough inspection with the mast on horses. You can check lights, sheaves, lube the track etc. You can remove the stays and shrouds and lay them out to get good measurments. You will know your boat better and get some peace of mind.
