I haven't done the direct so can't respond directly. However I was pretty amazed about the first anchor above Big Grassy on Ozy (original) - 2 big fat FHs right next to a perfect crack. (which M9 is hanging off at the bottom of this pic). I think/assume that there used to be original bolts there from the 60s - a time when maybe the bolts could be excused. But with modern pro you can get bomber #2-5 wires and small cams all over the place ... so I guess my comment is: just because theres old bolts there which have nearly died doesn't automatically mean they need to be replaced ... IMHO
yes I know thats how they do their belays in Yosemite and it astounds me there too.
