Another thing to do is clean the mast track. A sail on a bolt rope will do it. I had the sailmaker take a 12" length of luff tape sewn on a small piece of Dacron and had grommets put on top and bottom. Attach the halyard to the top and a chase line on the bottom. Soak it in a bucket with soapy water and run it up and down the mast slot a few times. Makes raising the main on slugs much easier.
