Thanks.
I usually do. This particular customer wanted a deeper chamfer on the frontside to possibly help mitigate some of the inherent "grinding" that plagues the Sram OEM XX1 28t's.

 I'd think that "grinding" could be diminished, when using Ti6Al4V, by removing some of the material on the center of the surface of the wide teeth, and perhaps by using a fillet instead of a chamfer.

 If one rode only in dry or even dusty conditions, I agree, that would probably be a better solution. In mucky conditions however, those features would quickly become filled and packed with mud and maybe even small pebbles which could potentially be dangerous if your cranks got locked up in the 12-6 position.

 Not if you let them be open in the direction of the center of the ring. Then muck will be pushed out that way.
