line test considerations

[MuskieBait]

Sensitivity - much more sensitivity from 6lb mono vs. 15lb mono (better feel for bottom changes, snags and bites)

Memory - much less line coil and stretch from 6lb mono vs. 15lb mono (better presentation with light rig or lure or bait when your line can be straight)

Suppleness - much more flexible with 6lb mono vs. 15lb mono (better presentation with live bait so the bait can swim around)

Visibility - much less visible with 6lb mono vs. 15lb mono (better for fish that is line shy)

Resistance - much less resistance in the water with 6lb mono vs. 15lb mono (affects lure action if there is too much drag from the line)

Stretch - much less stretch with 6lb mono vs. 15lb mono (better hookset and feel for the fight as opposed to fishing a rubber band)

Cast - much longer distance with 6lb mono vs. 15lb mono (less resistance and weight in the air to slow the lure's momemtum)

Yes, you can always use braid for the benefit of light lines, but sometimes you still need mono in areas with sharp rock or mussel shells since a sharp edge cuts through 30lb braid very easily, but using equivalent 8lb mono or better yet fluorocarbon will be a bit more abrasion resistant.
