Oops - I just re-read your description of the shot and (finally) noticed you said it's a 45-60 degree cut angle. I was thinking of the well known push shot at 90 degrees to the rail. Sorry for the misunderstanding.I can make this shot too, but not without obviously pushing the CB.
I'm interested to learn the shot you mentioned, Jay. Is it a "nurse" shot of some kind?
