Considering new stabilizer jacks

[GnP]

I have a 30 foot Capri travel trailer(2006) with round-bottom stabilizer jacks. To gain less trailer sway when parked, I am considering installing the scissor style stabilizer jacks on both the front and rear of my trailer
(maybe at the center points also ?? ).

I have also read about the steadysway stabilizer system as a possible addition to my existing stabilizer system (there by NOT upgrading to scissor jacks).

My question : Will I gain substantially more stability (1) with 4 new scissor jacks or, (2) 2 new scissor jacks at the midway points to my existing paddle-bottom jacks or, (3) should I consider a triangle crossbar system
(like in the steadysway product) to my existing paddle-bottom jacks ?

Looking for the least trailer sway for the bucks invested.

Thanks !

Before investing a lot of money, I suggest borrowing a friends between-the-tire wheel chock to see how much movement is reduced. They sell new for about $45 each if you decide to buy one. I have used one and it does dramatically reduce trailer movement.
I realize I did not answer your question directly, so here is my opinion. any "jack" will not eliminate front to back movement. The expensive stabilizer systems do what they claim, but the cost is a consideration.

Would something like this help out?
