I just replaced my old acoustic with a used excalibur 37/96 - 7/4 - 3/4. I am very happy with it...except for the bass strap. It is padded with leather on both sides. The top of my hand sticks to the leather making it hard move. Should I just replace it with one with cloth on the inside? Or is there something that is safe to rub on it to make it less sticky?
