The thinking behind Colin's team selection against the Ryman Premier League outfit is based on picking players who have yet to have a run-out in the first team games so far.
"Some of the boys have played games already in pre-season, so this is a first chance for the vast majority of the team," said Colin, who is able to call on the services of Gary Doherty.
"They have done two and half weeks of training so it has been a gradual build-up to this. If they can take their attitude in training and transfer it onto the pitch we'll do alright.
"I know Northwood won the First Division of the Rymans last season so they are now a Premier League team. Any team that wins a promotion has got to have a certain amount of confidence and a structure with which to go forward.
"We are looking forward to whatever sort of test they are going to give us. We demand that the boys are physically capable of dealing with whatever comes at us tonight."
Team: Eyre, Doherty, O'Donoghue, Foster, Barnett, Hughes, Bowditch, Black, Barnard, Yeates, Slabber. Subs: Henry, Jackson, McKie, Price.
