Is there any practical advantage to a lock using a roller-ed frizzen ? If so what is it?

There was a very good discussion back in 2010 on ALR on the history, merits, and problems from a roller frizzen. Just Google "roller frizzen". If I were to try to sum up that thread: "they look cool but don't offer any significant advantage, and can cause problems from wear and galling."

Hi,
A properly adjusted frizzen with a roller on the toe or on the feather spring provides significant resistance to the strike of the flint for an instant then when the frizzen rides over the cam it snaps out of the way very quickly. A similar effect can be achieved by bending the top of the feather spring into a slight hump, which you sometimes see on original locks without rollers. Here is an example I made.
Personally, I cannot detect any difference in ignition and ignition speed with well tuned locks with and without rollers in the frizzens. There may be but not that it matters to my shooting.
