The visciuos line in a mono line, it is a little softer than the other his/vis lines out there it has little or no memory. I have used Crappiemaxx his/vis line for years because it was so convienant to buy! The difference in the two is the crappie maxx kinks and twist worse than the viscious. It is a very smooth casting line. There is a line out there for every technique.

Casting- 6lb Visciuos
Vert jigging shallow- 6lb visciuos or crappie maxx
Vert jigging deep- 6 lb Power pro
Spider rigging- 10 lb Crappie maxx
Huckabee or double dipping - 10lb mono

Hope this helps! EB
