Don't let the negative posts above dissuade you from the FX84 by saying that it chatters. Keep it tuned 1/3 and ride it on edge and you won't get chatter at all.
You asked about it as an all around ski for the east coast and it would be a very good ski for an everyday ride. Are there better skis on hard ice, yes. Better skis on soft snow, yes. Better skis in bumps, yes. Better skis in trees, yes. But will there be one ski that can do all of these things very well? Probably not. The FX84 will do very well on all but the hardest snow and ice, and will be a good ski for some soft, fresh snow, and in the bumps and trees.
I'd bet that the MX series skis are going to be too stiff for you at 135 lbs. I've owned the FX84 and FX94, and the RX and MX88. I prefer the RX and MX88, but I have 50 lbs. on you. I would have chosen the FX series skis if I were 25 lbs lighter.

It would be worth getting if i already had a "newer" East coast hard snow/ice ski or as a backcountry ski but my priority is for a "every day" ski. I don't have any brand loyalty toward Kastle but will considr a MX series if i come across a good off season deal on them.
