I've heard this segment is a bear.

I tried this one in my typical 39/23, and it really kicked my butt... Note the extra curlicues by whomever made the segment. I have to work on some prep work before next year.

But, I agree, even carrying 20 or 30 pounds baggage, one should be able to get up any 10% slope of less than a mile or so with a 39/25.
However, the slopes get a bit rough once once pushes over 15% or so, even for short slopes.
