The spider web style on the top is an improvement, but, you have to realize that those bars are just for show. I am talking about the stock roll bar in the vehicle. Doesn't matter if its family or sport style, neither have a whole lot of protection value in them.
They might save you from a severe headache in a very slow motion roll over, but they will crush like a grape in anything worse. None of the attachment points are tied into the frame of the Jeep, and the fronts of the spreader bars just attach to the windshield frame, once it bends the bars get crushed down on you.
Unless you add the extra supports to tie the roll bar into the frame, then you are just wasting your money by adding family style over the top of a sport bar. It's just another piece of pipe that isn't much heavier than muffler pipe, and it's going to collapse just as easy as the other parts do, and even more so if you heat them up when welding them into place.
Please don't trust the roll bar that you currently have, and think that it will protect you in any way. I was in the Fire Dept. for 30 years and have cut my share of "roll bars" with the jaws of life in order to get a trapped patient out of their vehicle.
