I remember somewhere in Deakin's columns he states that about 50f ROP is the place most likely to do damage, which is exactly where many schools teach to run the mixture (pull it back until it gets rough, then push it in a bit). Any thoughts?

We never operate our normally aspirated IO360 above 75%, but do lean quite aggressively. If Deakin's statement is true, would we be better running AT LOP or are we going to risk damage to the exhaust?
