Forhand topspin technique

Hi i also have a question about my forhand topspin technique i feel there i have a Problem to find the right Arc on the ball because i personally think that i either Swing to much Forward and my shot has great Speed but to less Spin or i Swing to much upward and my shot lose Speed but has more Spin. Do you know maybe how i can set myself cues to really find the right Forward and upward path colleration. Because i thought maybe If i really will take care to hit the ball in front of my Body that this way maybe i also find IT easier to really get the right Forward and upward path on my topspin maybe also where my Racket ends Is a good indicator. Do you have other cues maybe that i could add AS a Addition to find the right forward and upward Motion for my forhand topspin against No Spin ?
