I'm presently working on a 14 years old Yamaha and the original pins are .272". I think yound Chang use these small pins too. That probably makes them more prone to twisting especially when the torque is high. I don't know the physic formula, but there must be quite a difference in twisting between a #1 and #2 tuning pin.
