Hi Slidepong,
Good question, its good that you are experimenting. Some players find dropping the shoulder more helps with their backhand topspin, take Kreanga for example. Whereas some players like TImo stay more level with the shoulders. See what works for you, I wouldn’t suggest over forcing your right shoulder and keeping your shot as simple as possible. Losing out on speed for control and consistency is much better in my opinion. Using your hips and legs is very important and the pivot from your elbow with the forearm and wrist.
