How much wider?
Starting from 90, you have:
Line Prophet 90 - stiff, prolly not great for park
Armada ARV (92) - soft, awesome in the park. I have a pair as my park ski, and I love them.
4FRNT MSP (92) - stiff, good if you like stiffer skis.
Line Anthem (93) - very soft, good for buttering
Then if you find yourself wanting to go over 100 mm, you have:
K2 obSETHed (105 mm) - early rise action going on, i'd imagine those would be fun
Personally, I wouldnt go much over that if you want performance in the park, but look into some of those for starters.
