Im sorry that i mistaked the AlphaX with other skis. Last week i was demoing skis for my local shop and i was on over 50 pairs of skis and it gets pretty confusing when people ask for specs on a ski.. As i am looking at the Armada catalog right now the AlphaX has the AR50 Sidewall, Hybrid Triple Zone Core (this is why they are stiffer), EST Park Rocker, Comp Series Base (Armadas Fastest base) , CK Stringer (Carbon and Kelver stringers used in the tail to add pop and extend life), Laminate Matrix (directional layering of fiberglass dictates flex pattern and torsional rigidity) and lastly the 2.5 Edge ( oversized and specially heat-treated, built to resist impact damage... So dont say that im just rambling a bunch of bull.. im sure you are just trying to make me sound like a douche just becasue your jealous that i have already rode next years skis and get next years stuff a year early.. but if you guys have any other questions about Armadas gear feel free to PM me and i will get back to asap..
