I like Icelantics. Super good company to the Denver community.
However, "the most durable skis on the market" I'm skeptical of until they publish their base thickness. To my knowledge, only two ski manufacturers use 1.8mm bases (compared to standard 1.3mm): On3p and J Skis. 4001 Durasurf are great from a durability perspective, and 2.2mm edges are solid. But still not the thickest / most durable used in consumer skis. That again goes to On3p with 2.5mm edges.
