I am sure that's true but its not a reason to prevent NDL racing. Rider wages are significant when it come to the long term sustainability of running speedway.
IMO Thomsen, Przedpelski are gone and either Doyle or Fricke depending on if Bewley makes top 6.
Emil and Atrum will be in with kim Nielsen who qualified. The rest will stay the same.
Its a shame Berlin doesn't have a covered stadium, because it would attract a decent crowd. Its very accessible from Poland and most of northern Europe.
So Waldstadion in Frankfurt is the other option. The advantage being is it has a roof but is it too ambitious to get a good crowd in when its so far away from the speedway heartlands. I personally think its too risky running a temporary track outdoors, Horsens was very lucky to get away with it.
