Best: Hensley Arrow or ProPride ($2500-$3200). Probably not necessary, but if you have the cash, buy one.
Great: Equal-i-zer or Reese HP Dual Cam. Different methods of sway control and implementation, same excellent results. I've owned both and like both equally.

Everything else: dunno.

The head angle determines how much weight is distributed. As the head is tilted down, the bars transfer more weight to the front truck axles and trailer axles. You should adjust the head angle until the front axles have the same amount of weight before and after hooking up. This can be done by weighing the rig or by measuring the wheel well height. If you use measurements, make sure you measure from the wheel rim. Measuring from the ground or tire might result in improper adjustment.
