If I was using line counter reels .... 30lb test braid with 6lb test mono leaders.
If I was using spinning reels ... 6lb test mono
.................... baitcast reels ... 8lb test mono
BUT ... it may also depend on which rods were being used, too.
All choices are personal choices on what I "would" use, but since I don't use either method to any degree ... I maintain the right to change my mind, should I start using those methods & encountered difficulties
