Frankie...You maybe have the ball bat in the wrong place. What we are concerned about is seat deflection causing loosening of belts, and the driver coming out of the seat in a major incident. This has happened, actually. The seats most people buy are the cheaper Saturday Nite style seats...They are not the strongest in the back area. If you can make yourself as rigid as you can in the seat/restraint/cage area, so there is no chance anything can happen, that is probably better. Of course, as Sprint Car guys know, a violent flip that keeps you in the car can result in bloodshot eyes, as that organ is sensitive. Still preferable to the other, though. I would prefer to see bars in a vertical plane, as per your `drawing`, but a flat plate reinforcement may still do the job. I don`t remember if the Lajoie, Ulrashield or Butlerbuilt `superseats` have additional runners in that area. Anyone know? I`d like to learn as much as I can about this. Would like you all to be as safe as you can be....
