the banana is really a park board, they advertise it as an all mountain board, but it lacks the stability needed for going fast. you'd be much better off with a Lib Tech T Rice, Dark Series, or Never Summer SL-R

if you want good bindings go with union, other brands simply aren't up to the quality of union, unions are the lightest you are gonna find and are totally bombproof. Union Forces or Datas would be good for the riding you do
