I got a great deal off EBay on a pair of 178s and have now skied them 3 times, twice at Breck and once at Vail. I'm not really good enough to give a really detailed review of the Top Fuel, but I'll tell you this much: I'm an advanced/expert skier and I have never skied a better ski than the Top Fuel. It absolutely rips. It carves so well, esp. at high speeds. It holds an edge SO well. My ability to carve steep blues and blacks this weekend at Breck and Vail got me so excited. I felt so confident to open these things up on the groomed. I tried alittle crud and powder, but I've only skied in CO 4 times now, so criticing the abilities of this ski in those conditions are hard for me, but I could sense that it floats very well, b/c of the 78mm waist. Plus the wide rounded tips really helped too. The real test for me was to see how these skis performed in moguls. I was worried about their ability to make short, energetic turns on steep, hard snow or moguls when I bought them. But much to my delight, they were incredible - I was short swinging very well on steep, hard snow, and was able to ski moguls better than ever. I really had a blast on these. Very energetic, fast, no chatter at high speeds, and there were numerous people on the slope asking about them over the two days. They are definately garnering alot of warranted attention.
