the airobic is a bit softer i believe, but the fun.kink will hold its own alittle better out of the park then the airobic.

ive only rode the airobic but according to there flex scale they are very similar.

the airobic has a wider flat base which should make it more stable on boxes and rails.
anywho, this is my list if i was looking for another pure jib board of what i would get:
