Cloud Tower - retreat/aiding

We'd like to get on cloud tower next week, but my partner (who will have to lead all the hard stuff because I suck) is worried about getting shut down on the sustained 11d-ish tips. Can that section be aided through? Failing that, what is it like retreating from those pitches?

Or should we just go get on Levitation 29 instead? The approach and short hours of daylight have me a bit leery of committing to that.

The crux pitch is easily aided (bring doubles of tips thru wide fingers). I felt like the last move of the entire climb was the real crux for me, after a very long day of climbing. Have fun!

Cloud Tower actually breaks down to a fairly short route...I have done it in 5 pitches with a 70m rope. It is not that committing. That means only two 5.11 pitches of which the last one is one. He won't have to retreat from it...mostly hands. Even if he did, that is where you start rapping anyway.You don't rap the route, but you do start rapping from the last pitch if that makes any sense. Breath, relax, think 5 pitches and go for it. One of the best routes we have, way better than clipping bolts on Levi. Good Luck.
