It has been posted in here before, but I will add to it.
Alot of the complaint stems from the fact that though Saloman was originally on the forefront driving the twin tip revoulution (but NO they were NOT the first), they have since sat on their laurels and fleeced the buying public with second rate poorly thought out and constructed skis. Cap construction foam core skis are CHEAP, they cost the manufacturer peanuts because they do NOT have to be pressed. There is very little material in them, a poly based foam that is injection molded into a shape, (high initial cost for molds, extremely low production cost per yeild) which in itself has NO natural strength, though it is very light, so in order to make the skis have any strength at all they must cap the ski with a fiber composite and resin. This is all great except for a couple of key points. First is that since the resin/fiber is the only point of strength, it takes only a short amount of time to break this structure down on a molecular level with the forces that skiing can apply, so in only a FEW (ten or so) days of aggressive skiing the torsional and longitudnal rigidity is lost. Second is that since the core is only a uniform peice of poly foam, it cannot provide ANY support to the steel edge. In a sandwich construction ski the edge can be pressed in between layers of the sandwich providing a very strong connection, this is not the case in a foam ski, and since park skis are used on rails, the lack of support leads to rapid edge failures (cracking) and immediatly after the broken rail will dislodge from the ski, as the only thing holding it is the net total of the edge, a broken element does not have enought support to stay with the ski.
So since someone just shelled out a wack of cash on a ski that they see Candide boosting on and doing rails on, and then use the ski for the same purpose and the ski falls apart.. the consumer feels violated.
