I think that this bag not working with your existing push cart is going to be a bigger issue than most people think.
I've been looking at this bag recently. I have the original Rovic RV1S cart. This cart worked fine with my previous stand bag, a Callaway Fusion 14. The leg hinges would fit right between the cart bracket where the legs would rest. I played a round of golf this past weekend and let a friend with a Titliest bag (not the Hybrid 14) use my cart. His bag would not sit flush against the cart because the leg hinges were too wide to fit in the cart bracket. So that got me to thinking about whether the Titliest Hybrid 14 would work with my cart. I looked online but couldn't find a whole lot of detail. So I pulled out a tape measure and tried three different bags that I have at home to see which ones would fit. Two worked because the space between the leg hinges was smaller than the space between my cart bracket.
I decided to head over to Golf Galaxy and check this out myself. When I measured the leg hinges on the titliest Hybrid 14, the space was greater that that of my cart bracket. Additionally, I tried the bag out with every push cart they had at GG (Bag Boy Nitron, TourTrek 360, Sun Mountain Pathfinder, Big Max Blade IP, there were a few others). This bag didn't work with any of them because the molded bracket on the cart where the legs would rest was smaller than the leg hinges.
I'm so discouraged. I'll keep looking.
