For climbing, 400g is worth around 20 secs per hour on a mountain climb, offset by any sailing effects in the wind. Super light wheels may offer a slight advantage depending on the gradient and wind conditions. But they may also be considerably slower in the wind.
If you take your head out of the sand and look around you might learn something new. But I know that isn’t going to happen.
