What is the thickness of the Coronation Ace Lite?
I do not have so much measurement data from the Ice Lite´s, but so far measured thicknesses has been...
Chromed area 3.80-3.87 mm
Chrome removal area 3.7-3.5 mm (as you said, this is a bit tricky to measure accurately and it varies along the blade areas)
If you are using 3/8" ROH in your blades, 0.2 mm thickness difference in the blade means 0.6 degrees difference in the bite angle. Thinner blade has less bite, if ROH is same in both blades. I know you are aware of this, but there are lots of people whom has not paid attention to this phenomena. You might need to change ROH if blade thickness is not same as in previous. Angle of the "chrome removal" has also own impact to the bite and it varies a lot depending how much edge has rolled (rounded) in the chrome removal process.
