I've read through most of this discussion and I go back and forth on whether to just go for it. Our current TV/TT/Equal-i-zer setup is working but I'm considering going with something a little beefier.
I keep pondering those chains though. All that stress and one "weakest link" would shoot through three cars before coming to a rest. I don't think the spring bars would do that much damage as they would be heading for the earth if they snapped.
The biggest drawback for me is the placement of the shock mount at the end of the chain. I have but two places I can place the mount and if they aren't at the right position at the end of the manufactured length or after taking out a link or two I'd be paying for the return shipping. I don't want to go through that.
I've posed the question in an email to their customer support but haven't heard back after three days. Anyone know the distance from ball center to retainer placement? I've looked but cannot find where they give any measurements.
