iceman44 found the solution to the weak flipper feel, as have many others, I have the ultimate fix for that problem. It's also a good sign that it appears JJP has tweaked something in this game to improve the flipper feel.
I'm really liking what I'm seeing and reading about GF, I can't wait to test drive one at TPF in a couple weeks. At this stage I'm certain an LE will soon be in my home collection!
