The riders have set -ups to suit the smaller tracks.Just some riders are unable to get it right.Armadale is no different to speedway in GB where mainly “ gate and go”.Skill and technical ability is what is required there.The best race tracks in GB are not “big” tracks.
eg
Redcar,Scunthorpe ,Glasgow and Somerset ( before closure).
Bigger tracks like NSS and Peterborough certainly also produce decent racing when prepared right.
