Replying to Help! I need a new skis. k++++

Im 159lbs and 5'9.

I only need a park ski and i might have a good deal on amplid syntax, armada ar6 or any alpha.

Iv skied park for 4 years now and I like to hit rails more than jumps but im ok in both.

Im looking for stiffer ski cos i had invaders and i didnt really love them.

I tried rossi s4 and they were really good so Im looking for something similiar.
