Matt, you asked about what we liked and what we didn't like. On mine, I really like what has now become popular with the roof halo and the external A pillar down bars. To me, no sense spending the time and money to build a cage and then still totally screw up the body with a simple roll over. It also moves the A pillar bars much further forward from where they are on an internal cage, helping the overall rigidity, and it makes it simple to run bars forward to the bumper.
I also really like the tube running forward under the front fenders. It still protects the body structure (fenders are cheap) without the ungainly look of a front exo cage, and it works. Mine has been over and that bar on one side took a good load, without it I would have had major fender, innerwell, and hood damage.....and still had minor fender damage. The grill hoop I also think is important, and I'm glad I did it. Besides protecting the radiator, it really helps to tie in the under fender tubes. As we know, structure adds strength and rigidity, so a few tubes does considerably more than adding thickness to the existing frame rails.
I like that all the hoops, A, B, and C, are tied into the body. The A down bars are attached to the cowl under the fenders, and the B and C bars are attached to the shoulder harness bolts. So the whole thing even forward to the bumper is tied together with the body. Adding rigidity and long life to the chassis was a goal as well as adding safety. Since it's possible to protect the vehicle and the people, so sense not to do it.
