Look at the video. Your arm and racquet are basically in line at contact. Your form is very consistent.
I understand that starting over isn't easy. I rebuilt my fh from a traditional, flatish old school fh (decent shot) to a modern fh. It took time and practice. But if you care enough to post a video, then you obviously care. Perhaps saying that you need to start over is overstating it a bit, but there are significant flaws in your basic form that will prevent you from getting to a high level bh. That's too bad because there are a lot of good things about how your hitting as well.
But that basic problem of the hitting structure is not a tweak, it's a pretty major fix. There are other issues as well. Watch the videos in the link. That guy knows what he's talking about regarding a 1hbh.
