For stand bags, the problem with using push carts has always been the interference of the stand / legs mechanism and where the cart attaches/rests against the bag. Callaway have moved the hinge mechanims down and created a 'low rider top' approach which avoids this interference. It means that you can use a Callaway new stand bag ( of the right model ) to both carry to the driving range as a stand bag and fit it into your clicgear or bagboy or whateber carts and it fits cleanly. See picture below for an example off the callaway site. Also if you watch the video on the callaway site, they show a low rider bag going into a cart holster.

So smart of them to do this. My clic gear can be a huge PIA with that issue.
