buzz for the purpose of training alone would there be any benefit in practicing a straight drive using stationary balls to get the correct movement and balance
well yes and no.
how often do you hit a stationary ball in cricket?
I think drop feeds (where someone stands beside you and drops a tennis ball and you hit it on the second bounce) are more effective as there is a timing element. But different people find different things help them, so I wouldn't say no, there is a time and a place for that kind of practice.
But as I said, your head position is more important that your feet position. Get your eyes/head in the right place and everything else will follow. If you move your foot first I believe you are going to find it harder to get right in a game situation - as you could end up with your weight going back (to move your foot) and then forward (as you try to play the shot).
Moving your head/eyes first towards the line of the ball keeps your weight and momentum going towards the ball which is what you want.
