It is interesting that you are experiencing more sway with the 1,200 lb Strait-Line # RP66084. Typically what we see is that weight distribution (WD) systems that are overrated for their towing setup cause the trailer to be more stiff.

Nevertheless you do need to swap out the bars for part # RP22225 which would then make your tongue weight range 400 lbs - 800 lbs and would be a better fit for your application.

Other things to help combat sway are making sure that your trailer is properly loaded (back to front and side to side) with a tongue weight between 10-15% of the weight of the loaded trailer. It also helps to make sure that you are not driving faster than the max speed rating of your tires. A lot of tires are rated at 65 mph but some are now compatible with 81 mph. You should be able to drive at least 65 mph without sway with this system.

Make sure that you are following the steps mentioned above and once you swap the bars out you should not really experience sway.
