I saw you were near the top of the tree on that segment!ha ha you're no slouch on that either - you know once I was nearly at the top definite KOM missed pedal and rolled down the side like a large boulder.
Yes it's a bitchin' climb! One mistake and you get the enjoyment of going backwards
btw if you were going to make up a YTs dirty dozen climb guide this would be one, monument another, bush hut, up to nowhere, the mega steep at kew boathouse have you or anyone gone up the climb that's normally a descent with switch backs down next to Johnson st bridge that finishes under bridge where you go up steps to do monument loop?
At the top of my head I can think of 6.....

The "Up to Nowhere" is a good one but I think the "GPS drift" tends to ruin the leaderboard. I did that climb in my big chainring (a 38) once because my front derailleur was caked in mud - it stung the legs a bit
the Bush Hut singletrack climb would be a good one as well (although I don't think I have done it up - ridden down it many times if that counts?!). I know the climb from the Johnson St steps to the top of the Boullie - haven't gone up it in a very long time (ie at least 1.5 years?!). You could perhaps also include "Starpickets Ascent" in that lot too
The Monument Climb is prolly the best of the lot. Rocky with a challenging entry point, it's hard to maintain a good rhythm as the rocky-ness can knock you off your line at any time. Plus the steepness means body position and technique plays a big role in climbing it quickly.
