Where did you get the tongue weight? You want the spring bars to be more than the max tongue weight you might ever have. So use 15% of the GVWR of the trailer as max tongue weight. Average tongue weight on a TT is 13%, but some (including mine) have closer to 15% tongue weight.
1,000-pound spring bars would be a max trailer GVWR of 6,667 pounds. If your trailer has GVWR more than 6,667, then I would go for the next size up = 1,500 max TW. A 2017 Jay Flight 26BH has GVWR of 7,000 pounds, so if your older 26BH also has GVWR of 7,000 pounds, then I would go for the 1,500 pound spring bars.
My TT has TW of 650 pounds, and I tow it with a ProPride hitch rated at 1,400 pound max TW. Works great. So I'll bet that a SwayPro with 1,500 pound spring bars would also work great to tow a TT with 1,000 pounds hitch weight.
I have the choice of 550-750# bars or 750-1000# bars. Which do you think would offer the best sway control and ride? I'm leaning towards the 1000# bars.
If those were your only two choices, then I would go for the 1,000-pound spring bars. Blue Ox SwayPro has more sizes than that. They also have 1,500 and 2,000 max TW.
