Wright didn't want Prem AFAIK, Iversen very much on Northampton's radar and that may still be the case despite his fall. Smektala also in the frame as well as others already mentioned on the thread.
It's far from ideal and hopefully the reasons for that will become clear but personally I wouldn't rule out going somewhere a month before the first fixture.
The main thing British Speedway does wrong is the lack of information even if there isn't much to tell and rhats happening here unfortunately.
If they have a motorway blade then stocks and speedway on the same circuit is not an issue. I can't believe its something they won't have thought about!
