this is a very subjective question as every ski is constructed differently and every skier utilizes these devices in a different way, thus abusing their equipment in different manners and to different extents.
Also, you are skiing this ski the entire time, no one else is in the equation, therefor you are slowly adapting to its slow metamorphosis into a limp noodle. Due to the slow change, you never really notice its inability to provide its initial characteristics.
At least thats what I think.
