Dalbello Panterra are OK , kind of all mountin boot , not much forward lean .
If you ski hard and steep, specially Carving ,I would go between , Head Raptor or Tecnica Mach1, (This is Narrow boots , so make sure your feet wide is not more then 98mm) .
I would Also Add Fischer RC4 The Curv ( if you have Narrow foot) or RC4 Pro if you have little wide foot. And do not go less then 120 flax.
I have Dalbello Panterra and Fisher RC4 Pro( my foot is 101mm) , they both 120 flex , they are day and night . Fisher is my every day boot, much stiffer boot , more performance boot , and I can fill big diffrence is curving, and .
Dalbello is very comfy boot , and I would say would be my powder ski day boot or relax day boot . They still good boots , but I would not call them big performance boot.
