For argument's sake (don't want to step on any toes): is it possible that the teams having problems on the banking is a result of a design flaw? Perhaps a small misalignment, which also causes a bending moment in the pushrod? Usually that's the cause for buckling (in combination with axial loading)
The funny thing is that only a small percentage of teams have had problems with the banking. I enjoyed it anyway
