I can tell the difference, and these are in piercings that are forty years old. I'm told that there is a difference depending on how the original piercing was done and where, but I cannot wear anything above 0.8 or below 0.7 comfortably.

My understanding is that 'gun' piercings are the most likely to be sensitive, followed by doctor's surgery/old fashioned jeweller needle ones, with modern hollow needle (piercing studio) ones the most able to tolerate wider gauges - not least because they're pierced wider to start with.

Argentium's great for making wires, but must be properly hardened - it's way too soft without both heat and forging.
