What does "at the maximum of" mean as applied to WD bars?
With the OP's rig, a TW of 625# would cause a load of about 240# to be removed from the TV's steer axle.
To restore the front axle to the unhitched value would require a load of about 480# to be applied to each WD bar.
Are you going to tell us that a load of 480# applied to a WD bar rated for 600# would put the bar "near or at the maximum"?

One possible advantage is that the difference in ride, with more flexible bars versus less flexible bars, might not be insignificant.
The less flexible bars can transfer more road shock from TT to TV.

Another possible advantage is that the difference in handling, with more flexible bars versus less flexible bars, might not be insignificant.
The less flexible bars will cause greater variations in load transfer when the TV's rear tires go through a dip or over a bump.

Another possible advantage is that the difference in fatigue loading on the TV's receiver and the TT's A-frame and body might not be insignificant.
The less flexible bars likely will cause larger dynamic forces and moments to be transmitted between TV and TT and vice versa.

Which hitch is the biggest seller proves nothing. If they do sell more of the 1000/10000# model, do you think it might be due to the fact that they do not sell an 800/8000#.? And, if you closely followed WDH selection discussions on this Forum, you would know that Equal-i-zer loses sales to Reese because the former does not offer an 800# hitch and the latter does.

Does that apply to someone who tows with a truck which "comes in at 6924# against a GVWR of 7050#"?
