For non-import stuff I think hands down Sufix Elite is the best mono.  Actually if you weighted price into your decision pound 4 pound I think Sufix Elite still wins.  The way its wound eliminates virtually all memory and its soo supple.

I use 2 brands of mono now and I would try a new brand every season on at least one set up to find the line that I liked the most. The 2 brands are Berkley Big Game, and I use it for my cranking set ups and Spider Wire Ultimate Mono, not to be mistaken for EZ Mono. The Spider Wire Ultracast ultimate Mono is thin, the 10lb has the same diameter as 8lb Big Game and it doesn't seem to stretch very much and has excellent abrasion resistance and knot strength, really pleased with it and I'm sticking with it. I use the 6lb and 8lb on spinning rods, the line does say optimized for casting reels but I found in 6lb and 8lb line with a spritz or two of KVD L&L that it handles fine, I'm really impressed with it.

If I am going to use mono, I sure am not now or ever going to pay that kind of money for it. That's just plain...well.......it is.

Defier Armilo is made just for topwater applications.  The regular Shooter Defier is for everything else. Great stuff. 

Dwight, I am not sure I would classify it as a one trick pony. I use it for all my reaction baits and feel it excels at it.

Big game, Seaguar!

I've seen people post that good old fashioned Ande mono is the best, and it's cheap enough to replace every season.

I am using the Armilo for all treble hook applications.

 

Another vote for big game, used it for the first time last year amazed how great it was on my baitcaster, performed very very well.

By castability, I'm assuming you're talking about how limp or resistant to spool memory it is. Mono will absorb water to some extent, eliminating much of the memory. It will also readily absorb line conditioners, which not only address any memory issues you feel it has, but it also makes the line slicker which contributes another factor into castability. 

There are many good mono lines, find one you have confidence in and stick with it until it disappoints you.  My guess is the only way it will do that is if you raise you expectations

If you want the best this is it. Defier is the Superman of monofilament. 

Spot on. Defier has exceeded my most optimistic expectations of what a premium Mono casts, fights and feels like!

Honestly, I could never go back to standard mono like Stren, Sufix or Trilene. Defier is in another realm.

Personally I like Berkley Big Game and Sufix Siege. Both work great for me and neither line is too expensive
