2 sway bars on a pull behind trailer

Based on my non techincal assessment of the Equal-i-zer vs Reese dual cam I can see one actual real difference and that is the Equal-i-zer produces an even "friction force" for all 'YAW ANGLES" where as the Reese Dual Cam "friction force" is larger the greater the "YAW ANGLE". Not sure if there is much advantage of one over the other except it seems that the Dual Cam would allow a trailer to "wiggle" slightly back and forth off the center line position since the friction force would be less for these very small "YAW ANGLES" than the Equal-i-zer which would have a larger "fricton force" for very small "YAW ANGLES". Also, it seems from all the posts by users of the Dual Cam is that it needs to be adjusted much more accurately to ensure the bar notches are on the cams correctly than the Equal-i-zer which doesn't have that concern.
