Sorry 'bout that - I thought that the windmall page had all the specs. Here is what is listed in the windmall catalog:
length width thickness
Surfstix 136 136 35.5 1.7
Surfstix 140 142.5 37.5 1.8
Surfstix 144 146 38.5 1.8
Popsycho 121 121 37 1.8
Popsycho 137 138 38.5 1.9
Bastard 4'7" 141 40 1.9
Bastard 4'10" 147 42 2.0
Don't ask me why the 144 is really 146, I don't know.
