Stu1961 separation
This is where I wonder if it's not an old rule related to wood/en heads or something like that and applying it to today's technology.
A crack in titanium is clear separation IMO and the fact that it actually needs to get worse before the rules allow for replacement seems silly, as it will 100% of the time get worse.
I dunno, but I suspect this will change....a d why is it a "local rule".....or maybe I should ask what is a local rule....i.e. something regional or specific to that location?
