I just ordered it from Copperstate Tackle. At that time all lb tests were available.

If Sunline Defier Armilo Nylon was as popular as it is when being closed out it still be available! 
Expensive mono line compatible Fluorocarbon the majority of anglers opt for FC. The price drop when being closed out attracted more users who may be disappointed it’s no longer available. 
No other mono comes close to Armilo performance; small diameter smooth casting with high knot and abrasion strength, but it’s academic now.

Tom, have you tried their Super Natural mono?

im not Tom but I fish supernatural for most of my mono (which is most of my line).  It’s a very soft mono, thin Japanese diameter for a given rating.  I fish 16# and 14# primarily. I think the 16# is about perfect for most everything largemouth that isn’t heavy pitching.
