I cannot see why he would want any lock-out really, why lug around a heavy fork and make them do nothing. Have you not seen the roads ? Worse than any bridleways
True, but modern lock out forks allow ~15-20mm of travel, rather than a fully locked fork, as it stops the internals from getting damaged.
High end lock out forks also have a floodgate, or blowoff threshold, which you can set yourself, so that you can choose the bump input that the fork will unlock with (& then relock)
Lockout doesn't add that much weight and is quite useful on climbs & the road (IMHO)
