Let me start by saying I am a free skier and have been riding a Connelly Concept for the past ten years. The Concept is a good ski, but when you get on something like the HO Coefficient X you quickly realize all of the Concepts flaws. I skied a friends HO Phantom that is close to ten years old also and loved the feel of it (faster, more stable), this is what lead me to the Coefficient X. My local shop recommended the Coex because it is similar to the Phantom, but with some newer materials and design technology. So I picked one up, went out on it Saturday for the first time and was blown away at how well it skis! It was only my second run of the year and I felt right at home on it. It is super fast across the wakes and really holds in the turns. I have only skied the course a handful of times, but I'm positive this ski will up my buoy count immediately, I know course skiing is more the skier than the ski, but I'm really feeling this thing (I will report back on this as soon as I get a chance).
Oh, for boots I got the double Attack boot, love them also! You get the comfort of a soft boot and the performance of a hard boot.
Here is a GoPro video of one of my runs from the chest cam angle, fun stuff!
