Personally, I'm happy with either a Cameron/Lacey or Cameron/Rawlinson combination with Slocombe in goal.
It's a bit of a quandary for me as to what formation to be honest. My issue with three at the back and two wing backs is that it forces our chief attacking missile in Roberts to play inside and he is far better out wide, but it would enable Taylor to play wing back and get forward, but then I also don't feel that Brindley is that great as a wingback. I prefer a flat back four, but I'm not sure of Taylor in a four defensively and I'm struggling to warm to Chicksen. He does some good stuff, but then will suddenly lose the plot for no reason.
All in all, I think we have a balance problem across the back, not helped by missing a ball winning midfielder like Bishop or Yates and a goal scorer. There are too many "but then/if's" with this squad.
