TST is an awesome choice for an all mountain ski that ready to shred all snow conditions. IT's very light weight making it extremely playful in deep snow and nimble through tight trees.
The other Ski that I would recommend for a little more stability at high speeds on hardpack days would be the ARMADA ARVti. Skied these all last season and they are incredible. 99 mm waist with a little bit of early rise gives you plenty of float for the deep stuff then add two sheets of metal for stability at insane speeds. Not to mention they're built by ARMADA, the best thing to happen to skiing since the one-piece. Check them out:
