My hammocks are still outfitted with these and it would take a LOT to get me to change. No muss, no fuss. I can set up my entire kit (hammock, UQ, and tarp) in less than 2 minutes. Or at least I used to be able to. That time savings is pretty huge in the rain/cold.

I see a few people have reported issues with getting the slide bars aligned... never seen that myself. I just thread the straps and pull tight. Never once paid attention to how the bars were sitting; they always seem to align themselves.

I know everyone seems to be using these whoopie sling things now... I'll probably look at them. At first glance though, they look to be more of a weight savings than anything else. As I'm not a gram weenie, I'd rather deal with a little extra weight than a little extra time being wet/cold. As long as I can keep my kit below 25 lbs. or so (3 day midseason weight with water), I'm happy.

Just my .02.
