The bottom sections of our lazyjacks are shock cord, they clip to the boom when required. We stow ours off the boom, on shock cords to the handrails unless we are dousing the main.
Though this creates an extra chore (setting them up and stowing them afterwards) it opens up the space between them for the hoist, making that easier, there are fewer chafe issues without the jacks in place at all times, and we use a regular sail cover without the hassle of fitting it around the jacks.
Being shock cord, though, they cannot act as a topping lift. We have a rigid vang/lift so that's not an issue.
There's an outfit called Ezee Jacks (sp?) that has a retractable setup too, but they are pricey.. though you could easily mimic their setup yourself. Some people swear by these too.
If our setup sounds good to you, PM me and I'll send you some pics. We're quite happy with them.
