Anyone know much about this line? How does it compare to something like YZ Ultrasoft in limpness, sensitivity, memory, stretch, etc? I'm specifically looking at #8 and #14

I have used both extensively.  In my opinion, AN40 is much more supple, castable and has less memory.  Yo-Zuri is much stronger, abrasion resistant, more sensitive and less stretch.

I suppose if you compare the actual breaking strength of the two fairly (and not the stated # test), the Yo-zuri would possibly overtake the AN40 in all categories.  For example, the YZ #6 breaks at 11.9 lbs.  The AN40 #6 is probably closer to 8lbs which is equivalent to the YZ #4.

So what's the conclusion? Is it worth the $5 to try out?  I'm going to make an order at *** soon and I need some line and they don't have Yo Zuri so I wanted to try something similar.

i paid like 2 dollars for mine :-?

Yeah, I think it's worth trying.
