Crows Nest 

I've only done the first pitch of the route. I thought the quality of the climbing was some of the best on the mountain. I also like the fact that there were great stances to place gear as frequently as I like.

Do pitch 1 & 2 together for a nice long stiff lead. Makes for an excellent climb that way.

It's not a squeeze flake. It's two lay back moves and your grabbing the top. Maybe 5.9 this way. try it you'll like it. Stay out of the squeeze!!

Like Rick says, doing P1 and 2 together make for a stellar climb.

For the local aficionado who's done this N times already, try the Electric Aunt Jemimah in Heat exit up at the top. That's the obvious set of left trending roofs. I recall that being fun and exhilarating.

However, I wouldn't call it the best route at Chimney.
For my money, that goes to EAJiH. That's the left to right girdle of the cliff. But then, I like girdle climbs. There's never a dull moment for the leader or the second.

There's some rotten rock near the start of both the first and second pitches so watch where you protect.

A #5 would protect the offwidth at the bottom of the third pitch better than a #4.

Among my favorite routes at Mt. Lemmon. Lots of undercling, lie-off stemming moves that go for 100+ feet. I found that two sets of cams from about 0.4 to 3 inches with one #4, a few wires and lots of long slings to reduce any drag made it very safe and well protected. It is really one pitch - why stop after 60 feet and hang when it is just similar climbing to the top and you can lower straight to the ground from there on one rope? Double your fun and do the entire pitch skipping the sport belay for the 5.11 climb to the left.
