As I mentioned above, I am using the 18lb flavour as I tend to buy my line based on diameter rather than quoted breaking strain.
The 18lb seems to be somewhere between the thickness of the 12 and 15 of my previously preferred Technium Black.
I've certainly had no problems at all with it knotting satisfactorily.
It sits on the spool nicely. Also casts very well, and sinks really quickly, which I like.
I haven't lost any fish on it yet, but having said that I've only caught one since I've been using it, and that was hardly a "monster" at about 8 or 9lb.
The only thing I have noticed is that I am getting a lot more "liners" with it.... could be coincidence, but could it back up what Wychwood are saying about it being more invisible to fish?? Dunno.
Jury is out for me on this line at the moment. Like I say, I am enjoying it's "bankside" properties but I've hit a barren spell with regards catch rate since going over to it, so not sure if it's the line, my bait, the fish just not wanting to know, or me being a numpty!
A few more fish on the bank will up my confidence with it.
I have bought a bulk spool of Technium Black to go on my spare spools "just in case".
