Extended downhills are almost next to never due to the local terrain, but it would be a good bike to take on trips with more climbing.
I do expect to ride in the wet with this bike, though. It will most likely have a set of fenders that will live on it and only come off for extended offroad adventures. I really miss having a bike with fenders because even the slightest bit of water on the ground makes me not want to ride.
If anything, the cleanliness of discs vs. rim brakes might sway me. The nasty black sludge you get all over your brakes and rims in the wet is my least favorite thing to clean off. And I keep my bikes clean because, like I said, I'm vain.
