So as i understood i should search line with the weight about 225 grains / 300 feet for #6 wt 9 ft, Right ?
Don't overthink this. The first 30 feet of a Rio Grand WF6F weighs 178 grains. That should be more than adequate to throw whatever fly you need to throw.
The only reason to go 200 grains or more is if you are throwing large streamers that have heavy cones or beads or eyes, lots of lead wraps, and an over abundance of hair or feathers (kinda like Kelly Galloup's Sex Dungeon).
