I'm starting my third year with Hartlepool.
First year I got promoted at second place with a mix of 5230 (Sky Bet League 2)
Second year I was doing really well with the original tactic of 5230 w/ away mentality. But somehow after being in the top 2 for the most part of season, the team somehow crashed in results towards the end and finished at 8th (Sky Bet League 1).
Third year I'm giving a try with your tweaks. Let's see how this goes.
Hope it will help you..GL!!!
