I respectfully disagree. A hollow g-loomis or sage is not the same molecular structure or process. Neither a bike frame or rod is strengthened by SS liner.
A barrel also doesn't have a thick clear/resin to chip or crack or fracture the same way.
Thickness of fiber is not even close comparison.
This idea of needing to check your barrel for who know what is bs, no more than checking my moly barrel for rust. Basic care will do both fine.
It wasn't accurate information. I don't care which way people go. Apples and oranges
