Thanks Ken, though I'd say a certain Ray Rice took over that mantle long ago.
Terminusout...I think bolt replacement and new anchors would be great, although even with that I doubt that they would ever be popular.
As far as the old pins go, thats a tough one....if you replace pins with bolts that would really change the character of what were pretty top end trad routes (hard E6's I would guess). A type of route thats just really hard to find in that they are really bold but still doable without prior top-roping.
I would say
Option 1 is to take the pins out and see if modern gear provides better/adequate pro ( a 1" cam was the smallest available back then).
Option 2 replace the pins. But remember the pins were pretty crap placements in the first place, so don't use the excuse that the pins weren't bomber as a rationale for option 3...
Option 3 take pins out and replace with bolts...last resort if removing the pins destroys the placement.
