Having rolled my jeep plenty of times, I am concerned with the material used to make the cage and the integrity of that cage more than anything. My current cage has been on it's lid at least 3 times that I recall. The only stock part of the cage is the B pillar. The front of the cage is 2" -.120 wall DOM with 1.75 .120 wall DOM winshield bar, door bars and seat mounts. The gussets are 1.5" .25 wall DOM. the rear of the cage is all 1.75 .120 wall DOM.
A lot of the mass produced "Trail" cages are IMHO not suitable protection for a hard roll let along multiple rolls since a lot of them use at best HREW tube, some are sch 80 pipe. Easiest way to tell HREW is to feel the inside diameter and you will feel the welded seam. My first rad hoop was HREW and I put it into a rock somewhat hard and that tube completely split at the seam, and I even had the seam on the inside radius of the bend. This is not to say that some bought DIY cages are not DOM or better materials, but those "kits" generally sell for upwards of $600 for weld your self.
