Weight distribution systems, which one is best?

I tow with a husky setup, always pulled a fifth till this unit, an Imagine 29 footer. I took the time to read and understand the hitch manufacturer's instructions, and couldn't be happier with the results,when I bought the trailer, the dealership mounted the hitch and showed me how it worked, but it was set up wrong. I read and followed directions in my driveway, can't believe the difference in how it pulls after me setting up the hitch and bars the way husky recommends. Education is important.
