Each to their own,and I agree that relaxing your grip often helps, but I still maintain that gentle countersteer used correctly and in response to sidewind keeps things in a straight line, as does weighting the bike with body positioning.
Motorcycles can be shifted off the intended line, or road position, by a side force of any description, it is the riders job, not the brainless motorcycles,to counteract the side force with an equal and opposite input.
