Replying to I'm about to buy Al Dente or TST.

Hello, i'm an 177cm,62kg intermediate skier. Here in Greece there are not lot parks. There is a lot of powder. I'm thinking of buying armada al dente but someone told me it is better to buy Armada TST. I want to go on some rails and kickers but mostly i will be out powder. What is the best choice for me(or if you have to suggest me other skis)? I'll be happy if you explain me the options.
PS: I'm new on the forum, sorry for my bad English.
