Wow, this thread moves fast!

I think Justin raises the ultimate point from my (and others, if I read correctly) perspective. Even if it were possible to conduct controlled trials of fishing line material on all pertinent combinations of external and internal factors, the variable of interest: "Does it shave well?" is vague and subjective. In order to get around that, you'd have to create a precise, measurable version of this variable, which necessarily means (in my experience anyway) averaging shaver's in some way. And the "average" shaver?: well, there's nothing average about any of us, I'd venture to say...

Even if you went with some more definitive proxy for what we really want to test, something like: "Is it sharp?", the link between that and "does it shave well?" would need to be investigated, and the problem raises it's head again.

Just some thoughts.

James.

PS Steve - time to lose the training wheels mate! In my opinion, you've attained jokemeister status!
