Replying to Help An Old Schooler Out Please!

Just wondering if someone could make the decision for me.
Kastle ZX 100, or Atomic Bent 100.
West Coast Skier, been skiing for 40 years. Still typically ski 40-50 mph on the groomers. Love moguls and trees as well. Don't send as many chutes as i used to, but a couple a year at Kirkwood if it looks right.
Both of these skies look fun.
I am currently on some older ARV 96 as well as K2 mindbender 108Ti.
A little help???
