I would imagine one's results would have a lot to do with the specific TV suspension, how much heavier the tongue weight is over the spring bar rating, and loading habits.
I originally had 1,200lb bars on my TV/TT combination with a loaded tongue weight shy of 1,200lbs and it worked great. A couple of years ago I upgraded to (2) 6V Deep Cycle batteries and some additional tools in my front pass-thru. The end result was that my loaded tongue weight increased to a tad over 1,300lbs but I experienced a noticeable increase in TV/TT bounce (static weight transfer was fine) with the existing 1,200lb bars. I went to the 1,500lb bars, readjusted the WDH accordingly, and found my towing characteristics improved.
Also, I do have heavy loading habits do to frequent extended traveling, so I tend to carry additional cargo in my TV & TT.
