I understand the frustration of the stock ones breaking "easily" and the thoughts about fitting more sturdy ones, but what would concern me is that if there is impact and the guard didn't break, absorbing some of the energy, then that energy is going to go thru to bars and force them to turn. It's the same reason that mirrors use RH and LH threads so that if they do get a clout, then they spin loose. They're there to perform a function, but there needs to be a fail safe else you're going to come off....
