Hey! It helps us to recommend you a ski if you tell us a little about yourself, such as:
Age
Ability
Weight
Height
Year of the skis you are interested in
and what bindings you plan to mount on the skis.
However, you are looking at 2 very different skis. The Armada pipecleaner is a stiffer ski, sandwich construction, and made primarilly for the park/pipe. The thruster is much softer, cap contruction, but also a park orientated ski.
In other words, answering the questions above will help me alot in trying to help you!
