Fly line suggestions for Sage Z-Axis 10' 4 wt

[Antoine Moreau]

I'm a new owner of a Z-Axis 10' 4 wt that I'll use mainly for Czech Nymphing, traditional indicator fishing and light streamer fishing.

I would like to find a fly line that will be easy to roll cast easily with indicators + weighted nymphs and also be castable overhead at good distance to swing streamers to river smallmouth bass.

Do you have any recommendations ?
