I wanted 165 but none were available when building my hardtail. I see no reason for not dropping to 165. And for offroad see better pedalling clearance as a benefit.
Ive got no comfort issues at the moment but if it was easier and cheaper I might try it out. But its not.
Don't like thinking im missing out on some free efficiency and possible pain avoidance.
