Maxima and Drennan Specimen ARE the exact same line.
Source of information: Peter Drennan.
Most lines are sourced from Japan, Germany or the States.
The biggest difference in most lines is the colour it's been dyed, it's manufacturer rating for a given diameter, the label, and the price.
Many times when you see a line advertised as 'incredibly low diameter for its breaking strain' it usually means that it has been rated closer to its true strength than exactly the same line from another manufacturer who has under-rated the same line (and which he may have bought in a different colour, or with no colour, ie, clear).
I have many a chuckle to myself when I see postings on this forum and elsewhere saying that 'X' line is much better than 'Y' line, when the truth is that they are one and the same line.
