Shackle your jib as low as possible and then control luff tension at the top. Most Tornados are now runing a 4:1 Halyard. The loose end runs down through the luff of the jib and then back to cleat on the beam with a 2:1 purchase. This will give you 8:1 luff tension which is more than we all used on our mains 10 years ago. Set the halyard so you can remove the majority once it is up.
