Cheers Grassy. If they stick to their guns then a run in the supreme seems highly unlikely, regardless of the ground.
In terms of the angle to take now (Aware you already have massive Ante post Exchange prices) I'm wondering if backing E/W with Ladbrokes NRNB boosted to 30/1 as highlighted by Danny is a the shrewd move. Alternatively, wait a week, hope he is declared and use one of the concessions (Sky & Coral already offering) of Money back as free bet if he loses and just back him win only as a bet to nothing - Hopefully still getting 25/1
