The one thing British speedway does better than Poland is having a points limit. You get much more equal sides, its not all about who has the most money to spend. I would put my house on Lublin and Wroclaw being in the playoffs next year, I wouldn't say that about any premiership side.
Grudziadz is a good track although we haven't seen the best of it this year, probably done to track prep. Definatly better than Gdansk, I would rank it better than Gorzow and Lublin.
