Hi All, reading through Joe's recent thread on frog positioning, the discussion touched lightly on the benefit of the thicker blades and chipbreakers on new planes (LN/LV). I was wondering if those of you with experience in this matter can speak to the benefits of using a thicker blade in an older plane (with old chipbreaker), and whether there is an appreciable improvement in performance if a newer chipbreaker is added as well?

Thanks in advance.
