I have the suspects this year, and overall there great. There one of the poppiest skis I have ever used, however there still quite playfull. There ok carving and not awfull in fresh snow. So overall as a park ski there definatly one of the best I have used.
Duarability wise yeah the top sheets suck, it does chip really easily but really who cares. The top sheet does not affect performance.
Edge wise, mine have held up really well, 40 days use no cracks, There is one section pushed in from hitting an upright, It pushed the base in a bit, but it has got no worse what so ever.
Overall, there great, NS will say they suck, but most people who say that have not owned a pair.
Like any park ski, some will break and becuase salomon sell alot of skis, you may hear about it more, but actually there durability is no worse then any other park ski, apart from the top sheets.
