Grooves help gain more backspin only in two situations:
1) Very low swingspeed (think pitches and chips)
2) Grooves channel debris away from between the clubface and ball, ensuring a more ball/face contact, and more distance.
Generally speaking, grooves in and of themselves do not create any appreciable, playable spin on a full swing shot.
