10,000 Restless Virgins 

The origin of the name? Per Sam Slater: "after leading this route you'll be as tired as if you had spent the night with ...."

And, note that Dick's Prick pinnacle is just about touching 10,000 Restless Virgins.

how can this route's amazingness be properly quantified?

the climbing is difficult, continuous, aesthetic, and varied. it is well protected. the location is unique and pretty, and the route is rarely crowded.

how lucky were those guys to show up in the 80s and find this thing unclimbed.

My first 10d (following) in the Gunks. Moves thru the roof easier than expected (with excellent coaching by my partner). The moves felt to me like an "indoor" sequence. The problems were to get over the intimidation, see how to start the sequence, and (for the leader) to protect it well.

At 169.5cm / 5ft7in roughly normal reach, I could grab the key bucket fully static, no deadpoint needed. I'd guess it would be much harder for someone less than 168cm / 5ft6in.

My partner leading found it less strenuous just below the roof to first quickly get in a couple of pieces, then hang from those while improving and extending (to a 3-point equalized config). Just above the roof I seem to remember a couple of pretty small cams.

Afterward TR ...
From the top anchor it's possible to do some (otherwise unprotectable) entertaining wide-chimney / stemming on top-rope -- between the main wall and the inside face of the pinnacle -- bring your camera (only place I know for this in the Gunks). Then for those with long legs, can move from the stemming onto the inside wall and try to climb a thin crack (much harder than Restless Virgins).
