I don't know what the consensus is, but Captain Kronos is the hardest 5.7 I've ever done at Josh, and is a real sandbag. Don't know if anyone else agrees with that, but I've done at least 100 routes in the 5.6-5.8 range in the park, and this was the toughest. It was more like an old school 5.9.
Totally agree on that one. The wider part mid way always fries me out just before the last crack/top out. I've yet to not have to hang for the last section above the horizontal cracks. And how about that start!
