Fantastic write up, very informative, thanks very much!
Regarding the crowns bevel and slope, this picture is a concern.....
The sloping is very pronounced, worse than the original T48 crown, there is a marked misshapen aspect to each of the ridges, as it tappers away, clearly seen in the crowns shadows and reflections. I really hope T stops the over polishing on these, because a sharp, square cut look is very desirable, and so far these crowns don't have that, unless they are PVD or TI.....
Cheers!
