wow, some passion in this thread...and happy customers for the most part.

First, I would ask, what do you want the line to do? Most lines are a series of engineering and or cost compromises. I have had good luck (with some help from Tom at ASM) w 20# Izor mainline in the salt running off riggers. I do use 25# Seaguar Flouro for leaders for plugs and spoons and 40-50# TripleFish for flashers.
As to cost, I agree w poster who said line is cheap compared to lost fish or dreams...
