Darnall, that was the whole intent of my post, not as an addition of support strength to the cage, but just to add that bit of protection to the top of the driver, like I sad, "keep the cows out", or at least deflect the blow to the helmet, that is a mighty big opening, and in some cases, things happen real quick, and that at least would provide something other than the helmet to keep another car out of the cockpit, I've had tires run over my shoulders, front wheels stuck over the side bars, and no problem, but a hit on the open cage might not be so pleasant, that was the sole intent of me wanting to add it, if the crash is bad enough, they will cut the cage off anyway, so what makes the difference, sometimes they will, just to practice! Thanks! Bob
