I frequently use that line in 6,10,12,15 and seldom 20lb. As a run of the mill line it's good. Through my experience, the memory is constant, it'll be coilly the first couple cast then softens up after being wet no matter if its been 1 day or a whole season. After this first couple casts it's smooth.
Far as abrasion, it's been above average when it came to toothy fish, 12 and 15 have been real good against pickerel.
For swim bait line it depends what you define, big? small? Generally pline's CXX line is more suited based on the crowd.
