Replying to WTB alpaha 1 or kung fujas

i know these skis are pretty different, but lemme know what you think........now for the details
i'm 6'2''  178 lbs.... whatever i buy will be used exclusively for park (189 hellbents for pow). i live/work in aspen so the x-park is the playground of choice. i'm about 50/50 rails/booters...and the booters are usually big 50-65 ft stepdowns.  i was thinking 182 for the alphas and 179 for the peps (the 189 peps looked too big for park). i like the idea of a fatter ski in the park, but the peps seem like they might be a little too soft for the big landings. also, i've been on ar5's for so long that the alphas seem like a safe bet. last thing....does anybody know how good coreupt tj's are or what they are similar too?
