The only thing i would say about it being all PL riders is that...
a) the field is wide open with no obvious winner
what i have found over the years at Berwick is that the EL riders simply do not turn up these kind of meetings, this may just be a Berwick thing, i dont know.
I personally think it is a decent line up and £18 is pretty good value for what will be good racing.
And im sure you would pay that to see a Tigers 1,2,3??
