I'm using QPR, having a lot of fun with it too. Gabbidon has been a complete failure for me so I'm getting rid of him and bringing someone new in, I've had a few bad games and a lot of good games but morale is looking good now. All thanks to a big 4-0 win against Oldham in the FA Cup :)
Edit...
Half way through my season with this tactic now, it's doing great, beating Arsenal 2-1 was a high point, but I've lost 4-0 to both Man United and Man City and I'm currently on a run of 4 losses in a row, so it's going to take something big to turn the morale around.
Any players we should think about signing in this mate? Looking at QPR's team they look abit weak in front of goal. Didn't seem to be a problem for you though.
