two guys I know use them...one in a buckley car designed for this yoke...neither one wins all the races or even seams to have any advantage...one lost a freeze plug and scaulded his sons legs cause there is no containment...when some racers are opting to use steel torque ball housings to protect their legs why would you consider the least safe way? Buckleys have been around 15 plus years ...you see how few use them..i don't see an advantage with a buckley over a standard torque ball set up
