When you're talking about how you're aligned right before you take that club away from the ball, Impact Fix generally just means that you set your hands slightly ahead of the ball, rather than even to it.
Ur right tho about your hips being open at the ACTUAL impact (actual contact with ball). I used to be confused with Impact Fix too man. It's easy to mix up...I think Fix (in the context of just before the takeaway) should have a different name or something...
