I'd be happy just seeing all the pins for aiming purposes, whether they're the same old pins or new ones. A course like Merion is hard enough with proper alignment on setting up your shots, esp. since as a TL my default winds are hardly ever user friendly.
I'm not sure but this lack of flag thing seemed to start on that foolish Clash when new flags were awarded with the tee markers for CC comps. One would think since there's an obvious starting point to restore to that it shouldn't be that hard of a fix that even an apprentice programmer could get the flags back in the holes.
