I have a great deal of affection for the League Cup too.Better day out than the FA Cup Final all the way around IMHO. More proper fans thus a better atmosphere, plus as you say at a reasonable price. The FA Cup has lost a lot of it's charm and status since the PL came on to the scene. The League Cup has pretty much maintained it's place in the pecking order over the years.
It's the fourth most important trophy we compete for. Far lower in status than the FA Cup.
