I say that it's down to preference, and what you are comfortable with to be honest.
The freedom of choice is a wonderful thing!
As it happens… my shoulders are of a 'barn door' type width and i find that my 710mm Easton fits me bang on… if that's o.k with you?
The bash ring is due to my increasing confidence, genuine neglect of the big ring and combination of more technically demanding riding where i feel that it will be of benefit. Phew.
