I find just the opposite. Grip Buddies and Puppies are too large and make my forearms ache horribly.Just to add to this thought.... I find many OEM grips are too small a diameter, and depending on throttle spring stiffness, causes you to grip tighter..... the fix, larger diameter grips.... Grip Buddies over OEM heated grips will conduct the heat and not absorb water. Other things you can do is wrap with bicycle handlebar tape.
