comment Are headaches a bad sign at altitude?
@Ben I always get headaches when I go above 9000 feet elevation. To your points: I slept well the night before, I ran a marathon a month ago so I'm pretty sure it's not "aerobic challenge", and I don't drink coffee. I live at sea level, 9000 feet gets me.

comment Warmth of two sleeping bags
My GF used two sleeping bags in Yosemite this winter, and thought they were over-the-top insanely warm. So, based on that one-time experience, I believe it would be closer to a -10-degree bags.

comment Lowe Alpine - TFX Cerro Torre: pack is moving to sides
Do you know how to adjust all 6 straps on a modern backpack? That also might make for a better question in this format: one that would be more generally useful to a lot of people. Just an idea.

comment What is this knee pain when going downhill?
I am not a doctor. But I have found a solution to my knee pain (which I think might be the same area): a lot of leg strength exercise. If my quads are strong enough, I can walk down hill (with a heavy pack on), landing heel first. This takes the pressure of my knee, and I can walk faster. Again, I am not a doctor.

@bhekman I forgot to mention the mental game. ESPECIALLY if you want to climb outdoors. Work on your fear. Put some serious effort into maintaining focus when you're in a tenuous position or are very tired. The more effort you put into this, the better you'll climb.

Rapelling. You will put both sides of the rope into your device when you rapel.

comment “Must Have” in a starter Trad Rack
A friend once told me that you shouldn't buy any gear until you know what climb you're doing, then buy the gear for that climb. (As a starter, a set of nuts costs little more than a single cam. So I just bought a set of nuts.)

comment How to warm up your cold toes and fingers?
Bonus points to anyone that can answer this question for rock climbers. There's nothing worse than trying to climb on frozen fingers.

Finger boards are key. If you follow a plan, and are careful to not over-train or hurt yourself, fingers boards lead to Fast Gains. Be careful and be smart. But finger boards are key.

Work on your finger strength training first, then on your technique, then on your core strength, and then very last you can work on your general fitness.
