Hello This line works well with the 8 wt St Croix Mojo Bass fly rod, as it is really a stiff rod. I tried an 8 wt Big Nasty line but it was too light for my casting abilities, and my air-resistant flies/poppers. The Bass II 330gr allows a long cast from one-backcast using a large fly. This combo is not a precision or delicate instrument, there is alot of mass being flung about - but it works. Highly recommended for either the Sage or St Croix rods. Gives great confidence to beginning bass- casters.
