They're both park skis, 1 mm doesn't make much of a difference. Neither one is going to handle all mountain and especially pow very well. You have 3 options:
1) get 2+ skis... either the chronic or the LTC for park and a > 105 underfoot ski for all mountain and powder.
2) get a ski around 100 underfoot for park and pow, such as the kung fujas, and realize it isn't going to ski park as well as an park ski, all mountain as well as an all mountain ski, and pow as well as a pow ski
3) get the LTC's or the chronics and learn how to ski pow with a center mounted, skinny, symmetrical ski... it won't be great but if you can ski well you can do it.
Be realistic about what you're skiing too. If you're skiing 90% park, 10% pow, get a park ski.
Life is brought down to the basics: if you are warm, regular, healthy, not thirsty or hungry, then you are not on a mountain. Climbing at altitude is like hitting your head against a brick wall... it's great when you stop.
Leave no turn unstoned.
