Replying to Kartel 98 VS 108

looking to buy a more stable ski for a trip to big sky in april and moving out west next year. currently on some center mounted 186 blends and theyre just too soft for high speeds. how are theses skis for charging big mountain type lines? i like the 108s but think they might be a hard on stiff moguls and have trouble in the midwest where i ski right now. 98s seem like theyd fit the bill quite well but i wanna have good deep snow performance . thoughts?
