To throw another ski out there: the Elan Amphibio 88Xti. I was skiing this today on rained over concrete, and ripping everything from chattery bumps to junk snow to SL radius arcs on manmade snow. Dang, this is a really good ski! It has metal, so tons of grip, but is soft at the tip and tail, so I get a ton of juice out of it. It reminds me of a 15m carver that really mellows out in off-piste terrain and junk snow. Kind of a hybrid carver with the off-piste ability of the Kendo, but smoother and easier for a lighter skier. I know the Kendo and Bushwacker will out-sell this ski 10 to 1, but neither are in the same class for how I ski, in terms of either energy, forgiveness, or grip. As far as the skis you mentioned: the Kendo and Steadfast are really expert-level skis with plenty of stiffness; Kendo has metal, Steadfast is a carbon layup that skis like it has metal. The Bushwacker (according to both Blizzard's literature and most reviews, including mine) is a mellower ski for advanced-level skiers.
The Blizzard you would want to compare to the others mentioned is the Magnum 8.5ti. That is their expert-level all-mountain ski in this range. 2 sheets of metal, bit less rocker, so much better on ice and as a carver.
