It seems to me that 28ga is sorta like the "industry standard" for coil wrapping. A nice compromise between resistance and stiffness that allows amateurs and "pros" alike to build great coils. I have other gauges but very rarely use them.
Sent with no malice and not a whole lot of forethought from my new Galaxy Tab 4. Thanks Santa!
Back in the day of clearomizers, 32 ga was the norm.
