CE Slide-a-link?

I have talked to CE they say can use them with any spring. Also spoke with Mike at Eaton Detroit Spring he says his springs work good with them. They say they are not as noisey as Cal tracs. Also with a more standard spring you can remove the link portion and drive the car without them. I was thinking about the 4 bar set up. But I want to use a dana with a 3.5" full exhaust. I don't think I can do it with the 4 bar. Was just wondering if anyone had any real experence with the Slide-A-Links. I think I am going with Slide-a-links, Eaton springs, and I have a set of QA1 double adjustable shocks.
