I like Pline and Trilene XL, and others too.
And I know you asked about mono.
But why not a light 2-4# inexpensive braid.
There's a bunch on the market.
It won't retain the coils like mono or flouro so it casts a mile, and it takes a truck to break the stuff.
Also, it's UV and abrasion resistant, which typically gives you longer life over mono or flouro.
Besides, with a small ultralight reel you won't be using a lot anyway.
When I'm jig fishing for eyes or other wary fish, I run a short flouro leader anyways.
Just a thought.
Good luck.
