You won't have any problems casting these braids. I would go even lighter in strength and go for something like a Fireline (Spectra type of braid) in the 4# - 6# ratings. Unbelievably fine line diameter and will last and last. No need to go stronger. And you'll be able to cast a country mile! Just make sure you use a fluorocarbon leader. Not for the "invisibility" factor, but for it's abrasion resistance. All braids need this, unless your fishing top water baits over open water.
