Replying to Which Twin-Tips?

Hey guys I want a new pair of twin tips for the park but also good all-mountain. I think i've narrowed my choices to the Volkl V-Pro, Line Maverick, Line Mike nick, Salomon 1080, and possibly Rossi Scratch FS but I don't know much about those. Of course you people probably know more about these skis than i do so which is best for me. The snow i ski on is usually groomed hardpack and some ice. Any help is appreciated!
Thanks, Russell
