The issue with silicone is how often you use it and for how long. Once a week for 25 years? You are in the toilet. Once every year for 3? Not nearly so bad. If you have it in the back of your head that one day your bass will become a highly coveted instrument, avoid it like plague. If you think it more likely your great-great-nephew will one day use it as a bow to shoot arrows? How much does it matter?
