It wouldn’t hurt, I will say I am not that experience after all I really started yoyoing a couple months ago. I’ve been figuring things out by trial and error. This might be a shot in the dark but have you messed with the axle or possibly tried swapping it. The way I view it is there’s some sort of imbalance between the halves if you ruled out how it is thrown (not saying it’s your throw)
