Just found this thread and slowly making my way through it.
GOT is an amazing game, in fact, it's the most interesting game I've ever played in terms of scoring and strategy -- and it can easily get better by rebalancing the rest of the houses that are not Greyjoy or Martell
GOT is also by far my most favorite Stern game.
After initially being disappointed with the flow of the GOT LE as compared to the PRO I like it much better because of added variety in gameplay: plus, the PRO just feels kind of cheap, relatively speaking. I do admit though that an LE is much easier to gain control on.
For newer players I would suggest that they key to long ball times is learning to live catch balls coming out of both orbits. Especially the right orbit can be tricky because the ball can hit the top of the bumper. On location, I will often hit the right side of the machine OR move the machine slightly out of the way (if you watch Keith Elwin, he does the latter).
I have put in a lot of time learning better mechanics but it's been extremely rewarding -- something I can not say for the latest Stern release :/
