The climbing between the first and second bolt along the crack is unprotected and much harder than .11b. To keep it .11b traverse right after the first bolt and work your way up to big knobs before climbing up and over to the second bolt. (Big runout here which could result in hitting the deck). After the second bolt the protection gets much better and climbing is much easier. There are 8 protection bolts dispite what the guide says. The crux of the upper section is just after the 7th bolt and is much harder than 5.10d, more like 5.11d but well protected.
