I ski Volkl Mantra 184s at 94 underfoot for all conditions. I've noticed I can ski any moderate fresh up to say 18" with no issue. Friday and Saturday it was more like 36" of fresh and I got into some trouble on the Mantras with tip dive. Thinking back over the past few seasons, all my wipeouts tend to be from going over the handlebars after one or both skis get extra loaded with snow and stop while I keep going.
It happened several days at Alyeska in super heavy pow. It's happened two days at Alpine Meadows on 36" or so of Sierra Cement, it happened at Squaw Friday in 36" of relatively light powder and yesterday at Sugar Bowl in about the same.
I've had the Mantras 5 seasons now through about 120 days and my skiing has gotten so much better as a result. I think skiing the same skis has really helped me figure out their strengths and weaknesses. It has also helped me to be much more confident on them. Aside from one day in Alyeska where my skis didn't make the flight (skied Blizzards) and one day at Squaw (Head Mojo 94) where I needed a full tune, I've just skied the Mantras.
I talked to a salesguy at Kirkwood after checking out all the new rockered fat skis and kind of laughing at them honestly. He spoke very highly of them and showed me the early rise/dual rockered skis that were out there. For the 2-3 days of super deep stuff I probably get a year I'm having trouble justifying setting aside the Mantras. In the right scenario, a demo day might be in the cards but I travel long distances to the mountain and can rarely get there for first chair on a powder day without factoring in the demo time.
My question is what kind of techniques can I apply to the Mantras to keep the tips up and eliminate this weak spot in my skiing?
