You are correct, sir: absolutely zero experience with that.
To me, a "used drive belt" means its strength is compromised, and it was replaced rather than risk failure.
Glad it works - so far - for those who use that method, though.
Not at all. As I mentioned earlier, the salvage yards are full of belts that were fully serviceable when the vehicle was killed. A simple close examination will reveal it's condition. Same as with a chain or anything else you would lift with.
No one is trying to convince you to use anything other than what you are currently using. You are only looking for reasons to support your decision not to use belts while ignoring many, many real experiences with them.
Carry on.
