What did Hensley quote you? The two companies you mention-Hensley and ProPride-absolutely hate each other and will do whatever it takes to steal a sale from the other guy. They are essentially the same design and work magnificently, albeit at a much greater cost, weight, and complexity of installation/hitching/unhitching.
I ultimately went with ProPride because I liked the responsiveness of the owner (Sean Woodruff) who has been very quick to respond to my questions, even after purchase.
If you want to go the capital investment route with your hitch purchase, I'd certainly drop Sean a line. The website is here:

After the titans were finished with each other, the price I paid was many hundreds less than advertised.
These hitches absolutely eliminate sway. Period. I recently took my 35 foot TT through a mountain pass in heavy cross winds, and if it weren't for the lean of the trees, I wouldn't have known it was windy at all.
