Replying to Volkl Karma OR fischer addict pro help???

mt local shop has these both in stock and on sale for $350ish
so i did a thread search and this is what I am guessing:

Karma - stiffer and wider so better in pow but less so in park

Addict- better switch b/c true twin, and the only other thing is that people seem to really like the ski but I do not really know why

i am 6'1" 170, I like to charge hard out of the park and I am aspiring but more tame in the park.
