Route is difficult to follow, and it's very easy to end up in very technical situations by mistake. Also, the heat is so bad that it's nearly impossible to bring enough water (plus too much water weight my slow you down).
I would recommend bringing lots of water and leaving some of it for the way down when the climbing gets technical.
I also wouldn't recommend doing this route alone. Cell service is scarce, and you probably won't see another climber out there all day.
Stumbled across this on someone else's site and had to check it out.
