The coloured Amsteels do shed their color so you might consider grey. I've been using 3mm grey for my jacks for about a year now and am very happy with them

The way mine are made up is that they go under the bag, around the boom such that they hold the bag to the boom. I have them fastened to tabs on the stack-pack so they have tension to hold up the bag when deployed

this is the only pic I have of the jacks. What you can't see is that along the top of the bag, instead of battens and straps to tie the lines to, the lines you see are run through grommets which have plastic balls knotted to them at a length such that when tension is brought on to the jacks, the bag is held up, but the line length run under is left slightly loose as you can see

I think I understand how you have your lazy jacks run through the stack pack which sounds exactly what I want to do. I started with lazy jacks, later fabricated a stack pack and then took it off because I did not like the battens which were a mess while sailing. I want to go back to a stack pack and would love to see more pictures of your arrangement. Would you mind?

Multi, thanks. Since I don't race, i would almost always sail with it on and not tied down. With a batten, the one I made just had too much bulk flapping around. I'm hoping that without the battens the windward side will lay against the sail and not create a lot of disturbance.
Thanks for your posts.
