I would also say ET. If your not jibbing, the airobic's massive flex is going to be very limiting. On the other hand, the riot is relatively stiff - it's super stable and great for booters, but not the easiest to ollie and butter. ET is the best of both worlds.
Alright, luckily there is one Evil twin 157 cm left. I have last years forum kicker slr boots. Last year I tried burton fix and i loved it, but hated the k2 WWW. Maybe is should get a rocker board tho? So my last question would be : What would you guys rather get? Flow Verve 158 cm (-4mm camber) or Bataleon evil twin 157 cm ? The price is pretty much the same around here.
