The CB to restrict the roll rate was there for a purpose. Excessive roll rate can cause what is called "roll/yaw diversion". This will happen at high speed at low level (lots of air for the ailerons to work on!) Effectively the aircraft starts tumbling. Of course at high speed the aircraft will break up. This happened in front of the CinC when he was watching the years approval of the that year's display pilot (no names, no pack drill). The arrows pulled their C/Bs and got away with it. I suspect because they never flew at warp factor nine when thay were rolling. I was involved with the aftermath.
