The Park End build was a disgrace. It is cheap, out of context with the rest of the ground and betrays Goodison's pioneering history. Many clubs have built and moved or even rebuilt stands since 1996, the heirarchy's record on stadium mgmt is abysmal.
I get what you are saying regarding a shallow rake and I quite like it at the GS though we shouldn't be selling the seats at the back as the views are unnaceptable. I wonder if it's a case of familiarity though as I have to say I'd quite like a massive steep stand behind the goal. Below is Juve's lower rake compared to the St End and I reckon theirs looks more intimidating. I know Tom Hughes is his work on designs states that we should aim for a mixture of different types of seating, in part to recreate the feel we have at GP and I'd love us to go down that route. I can't see many new footy stadia being built with a shallow rake these days, it takes up too much space.
