Hey Equalizer people, which one should I get?

First off, the Equal-i-zer hitch works great. I tow with one currently. However, once the paint wears off the weight distribution bars. You will hear the most God awful “Nails on a chalkboard” sound you have ever heard. The first time it happened to me. I had to take the bars off when I arrived at the campground. It was extremely embarrassing. I did make one mistake though. When I bought my new TT the hitch was setup to and empty truck and trailer. I did not touch the hitch after that. I have since loaded the TT with everything I thought I would take with me, and also loaded the truck. Then, I setup the hitch again. I also purchased the bracket jackets for the L-brackets. The noise is almost completely gone. I am now able to drive into the campground without waking the dead.
Equal-i-zer tells you that the jackets will reduce the amount of sway control, but I have not noticed any difference in the amount of sway control.
