I used to think that a high crown in step cuts in a must but not anymore. I once had an EC that had great stats on paper with table and depth under 65%, medium girdle, VG polish and symmetry and the loveliest steps and a fantastic crown (12%), but it does not sparkle as well as my new EC which also has great stats on paper, other than a lower crown when viewed from the side. It isn't flat but is certainly not as high as I would prefer aesthetically. The first EC was purchase locally without ASET and the second is from JA with ASET.
It leads me to 2 conclusions:
1. Great stats on paper is insufficient (which I'm sure most of us already know)
2. A high crown height doesn't guarantee good dispersion
What I'd like to know more about is how crown height plays into light performance. How can a great performing EC still get away with a 10% crown height and why doesn't a 12% and higher crown height "save" a mediocre EC.
