Ok guys, my order is probably going out tomorrow. I'm going to order some Edge wool pads and I was wondering how they compare to the LC Purple foamed wool. Is there an Edge pad that is equivalent, or do I really need to have both. I have the E2K system, which I love, and the constant raving about Edge Wool has me wanting them. What can you guys tell me about how they compare? I'm kinda hoping there is a direct comparison so I dont need to buy both. Thanks guys.
