However, I agree that the new X plastic is markedly inferior.
My stock XL arms handled some insane abuse before I put an (1) RPM arm on the L/F lower after 6 gallons.
So I guess they still use some decent material.
It was cracked at the hinge pin for a gallon or so before it broke.
And I screwed it back together for another few runs.
