People seem to worry most about the north side loops. That grade is long and steady, but I don't think it is exceptionally steep. And the corners look sharp at a distance, but up close I doubt if they are worse than a city corner.
The south side of the pass also has some loops, but more spread out. But I think the lanes are narrower and with less of a shoulder. I believe there was some construction to widen those curves, but I'm not sure it they have improved them all.
If you have adequate power, including braking power, the curves themselves shouldn't cause problems. It's pressure from yourself, or other traffic, to take grades and curves fast that is going to give you problems.
