short boards are awesome jvee!
I ride a 152 con artist and it's great. Hovercrafts are good too. They ride hardpack and gnar just like a regular board. It's got a sick profile.
I've even used a 150 nug in the deep stuff no problem.
Whether to get a 56 or a 60 hover, for your weight, I'd be leaning towards the 60. It will handle like your arbor but give you crazy float.
oh, I've got a 160 fish that's just lying around if you're interested.
What would you want for the 160 fish? i got a lobster.... freestyle.... in 157.
