Syphon, do you have the 3.3 revo or the 2.5 revo?
The reason I ask is that the RCS cage's rear is relatively weak if it's a side impact of any type due to the length of the gap between supports.
The are great cages if you land directly on the roof though. Would be nice if they would let you buy the pieces you destroy vs replacing the whole cage.
Although, I am basing my experience off of having an RCS cage on a savage, which is a taller and heavier rig in general. I folded that thing up like a pretzel. It did it's job though. Didn't loose an engine, but the cage was toast.
I tend to go with roll bars now. Usually some roll bar I come up with that uses stock roll bars or just flat out my own, like on my aftershock. Usually not pretty, but like you, I drive hard and it's great to go burn a gallon of fuel and not have the day ended due to an engine ripped in half or shock tower snapping.
