I have the MX sails. I altered the typical ring setup to one that allows me to adjust the luff tension while under sail. In addition to a sheave up top on the pigtail I added one at the bottom where the forestay meets the jib-pole. From there the jib halyard goes thru a 3:1 purchase before going to a jam cleat on the main beam. The line that goes to the main beam is separate from the excess line that is leftover after the jib has been raised. I connect these with tiny shackles that require a slotted screwdriver to tighten and loosen. You have to have a steady hand if it's blowing when you are trying to set sail. Otherwise it works great. I'll send photos when I get my boat rigged this month if you are interested. Greg
