Seems like your strength is a flatter plane. A weak fade or a pull suggests an out to in swing path; fade when the clubface is open to the path and pull when it's closed. If you are a 10 handicap all you have to be is aware of the fact that I just described. 3/4 swing is very wise so I'm surprised of the possible "over the top" trajectory.
At the top of your backswing, in your case 3/4, make sure you are holding that club passively, transfer your weight to your leading side and just let the club drop right in.
I like the drill of feet together, swing back and downswing taking a shoulder-width (or a bit more to emphasize the concept) side step with your leading foot towards the target.
I hope this helps,
