Enemies are perhaps the best at all-mtn. skiing for twins, but their durability is questionable. I have Dynastar Concepts, which are above average for all arounders, but have a few stress cracks in the tops from hard landings in the park. Line's are great park skis, but are lacking quite a bit in the all-mtn. department. Pow-airs, V's and 1080's are good for all-mtn. use, too. Next season, the offerings are changing dramatically. If I am going to rip runs and the park together, I use my XX's. They are light enough to spin, land fakie nicely, but rip everywhere else.
