So just to quickly update -
I bought myself a tub of Fuzion and can say it just about eclipses Cotton Bacon - yes it does cost more but you get a lot of cotton and I've found it has just as low a break in but it wick somewhat better (willingly) and taste testing I'd say a bit warmer - if you know what I'm saying. Fuzion seems to be coiled in the tub and is very easy to pull what you need and I've found I'm wasting less than I would with CB..CB v2 is still very good but would say on balance it is just pipped to 2nd position.
Next up is either Fuzz organic or Texas Tuff and I'll pop back with another small update.
