I was having fun reading through old guidebooks lent to me by Roboboy and comparing old descriptions to newer ones. Of course many routes that were aid went free. Usually the rating went up but sometimes it went down, either due to sticky rubber soles or cleaning of the route. A few examples follow:
Orbit (1965), 5.8/ A3, 33 pitons, 4 bolts
Orbit (1996) 5.8+, four stars, Pro to 3"
Remorse (1965), 5.7/ A2, 40 pitons, 5 bolts
Remorse (1996), 5.8, two deathheads ®, Pro to 3"
White Slabs (1965), 5.9, 12 pitons
White Slabs (1996), 5.7, Pro to 2"
White Fright (1965), 5.7/ A4, 20 pitons
White Fright (1996), 5.9+, one star, Pro to 2"
Saber (1965), 5.3
Saber (1996), 5.4
Saber (2004), 5.5
