Replying to Good Ski for pow and tracked out snow

I've been on line sick day 110s for the past 3 seasons, and I think this season will be their last. As I've started to ski more agressively I find that the sick day just cant handle being driven through crud and tracked out snow. I find that it gets deflected around every which way and doesn't feel very stable at speed. I'm 6'1" 190lbs and I primarily ski the Canadian rockies. I've been looking at the ON3P billygoat but to be honest I'm worried it might be too much ski for me (ie. TOO stiff). I've also been checking out the 186 ON3P kartel 116, do you think this ski would handle what I'm looking for? Any other suggestions for a ski that can float powder and be moderately playful but also slash through everything by the end of the day when it's all tracked up??? THANKS
