Sailing my new used Wave with the stock 4:1 mainsheet blocks. The boat came with a pretty tattered mainsheet. I was lucky enough to find a 30' piece of 8mm New England Rope Buzz Line (poor man's Salsa) in the APS end of spool bin. I have the cleat in the top position to prevent an accidental cleating, but at that angle I found the flairlead over the cleat gave little space for the 8 mm line to run through. I added a couple of 1/2 nylon spacers between the cleat and flairlead. This also helps when uncleating because the line has more room to snap down. Here's a photo.
