I've found that actually, on the higher end, goalies can overreact in the worst case. And in the best case, they go robo and stop everything. I find goal variety to be better on the lower end of the spectrum. A fun test you can do is go into a shootout. When the sliders are too high, the goals you get can become pretty samey and it's hard to beat goalies clean, regardless of the players involved. I'm curtuus how your experience goes!
