There's nothing at all wrong with feeding live asking as it's done responsibly.
The pros to F/T : can bulk, saving money. They NEVER fight back. Don't need to keep refusals alive. They're MUCH easier to find for most people.
I 100% agree, wasn't trying to sway OP's opinion just offering mine. Like you said as long as you're feeding responsibly and not causing issues for your snake based on your choice, I don't see an issue with either method.
