Replying to K2 domain sizing help +k for help

looking at the 2012 k2 domains

wondering the 179 would be right size for me

Im 5'11" but will probably be 6 foot by the winter

weight:160 lbs, again maybe more by winter

ski all park in pennsylvania and go out west each year to colorado possibly mount hood next summer

about an intermediate park skier, been doing it for the past year or so, and I think im alright

would the 179 be the right size?

+k for some help on this or if you have another ski to suggest for me
