I assume its a max of 2 riders per team so that rules out Perry. I have no idea about Williamson but maybe Shanes has a grasstrack meeting. As well as Williamson, the only 2 overlooked are Atkin & Hopwood, maybe Atkin wanted to give a younger rider a ride! He only seems to want to ride for Buxton these days. Stokes is replacing injured Knight for KL. Then the next 3 in the averages are Ayres, Owen & Mountain as everyone else is injured! But they'll cover their bases and call them wildcards!!
My prediction: 1st Branford, 2nd Ellis, 3rd Hughes & 4th Morley.
