Yeah, I used cotton bacon when it first came around in idaho. Its literally just medical-grade cotton, theres nothing special about it and japanese cotton is superior in almost every way (neat square-ness, flavor, wicking ability). Japanese cotton is definitely better than cotton bacon, but both are decent wicking cottons.
Organic cotton balls are dead though, I tried wicking with one lately (after a year of not using cotton balls) and it was the worst thing ever, absolutely horrible.
So yeah, cotton balls suck cotton balls, cotton bacon is good, and japanese organic cotton pads are better.
Hemp wick is also worth a try, its got an earthy, planty taste to it and looks like tangled fuzz but if you manage to wick decently with it, it sucks in juice like madness
