As much as I love the subway on GB Premium/LE I detested the way it flowed in comparison to the Pro. The Magna-Slings weren't my cup of tea either. Someone recently asked me why I went Pro over Premium/LE and when I explained it he casually retorted with "Oh, so you couldn't afford it, gotcha. Dude, you ALWAYS go premium with every pin, hands down."
That kinda attitude is just lame and really weird. Some features are either not worth the higher price point or don't matter to some people. Walking Dead, Black Knight SOR and TMNT are some others I can think of. I'm sure there are many more.
