I find a 350 grain wet tip express fly line (SA) about perfect for much of the salmon fishing I do with my 9 wt one handed rod. I would like to set up a similar line (350 Grains) for my spey rod. It is a 14' 9/10 wt St. Croix. What are the alternatives to lead core attached to the end of a Rio mid spey floating line (8/9wt) which I have. I don't like casting lead core. Thanks in advance. I'm new to spey casting.
