I have lost my mind with that wrist whipping action but you need to be relaxed and use the kinetic chain. When i'm thinking about pat the dog, etc. i just can't be relaxed and it effects my game.
So now i'm using my hitting arm passive all the time. I can't give it a loop because i don't feel any muscle stress in the non hitting arm. The backswing happens with the sudden turn of the shoulder and pushing the hitting arm with non hitting one. After this, when i turn my hip, i can clearly feel the kinetic chain pushing the racquet forward. Looks a bit like marcel granollers's straight takeback;

Do you think that kind of backswing can improve my game, or i should just find another solution to the problem ?
