Replying to M1s or Rubies or Helix?

 Ok... so i created a thread earlier... and it was for M1s against gotamas and i decided that the M1 would probly be a better ski for me...   But then someone in the last thread said that Rubies in a 190 might be better than an M1 182 for me... And when i contacted Moment they said that the rubies might be better also but they said either one would work pretty well for what i want... What i want is a fast ski thats manuverable and can ski all mountain in the east coast ( up around jay peak/ mad river glen area ) but can also handle the the powder out west or in chile... someone said that the M1 is not great for real deep stuff which i will get on my trips west and south to chile.... Another ski which looks interesting to me is the liberty helix.... i dont know much about the helix but from what i hear they seem to be a great skis all around.... I am 6'2 but am still growing and could be up to 6'5... However i am very light.... i weigh 140 lbs.... I tend to like really stiff skis...  And i like to ski glades, bowls, chutes and just some groomers...   Can somebody give me some advice on which one of these skis or if they have another ski in mind would be best for me? Thanks...
