Clubs fit.

I've got a great looking set-up and backswing that you have seen.Flat left wrist at the top but something bad happens on the downswing.

If your hips slide towards the target would this change the path of your swing?

I have better luck when i play from an open stance but as soon as i get square the ball starts going right.

A little hip bunt forwards to start the down swing is commendable but if you have a tendency to overdo it or slide the entire upper body forwards then you have, effectively, put the ball back in your stance.

Moving the ball forwards in your stance at address or restricting your forward body movement on the down swing should solve your problem.
