I was gonna get some TM's but my brother and his friend both have problems with thier edges falling out. What kind of skis would all of you recomend me getting if I ski alot of all mountain and backcountry stuff out here in Colorado but I still want a ski that I can use in the park. I definatly still want a twin tip because I like to spin on all the natural jumps I can find. Thanks in advance for your help.
