Bluecod,
I have a WF floating line I use wading sandflats but after I get the new boat will be going after the salmon kings etc. on fly.
Been in the backyard pool counting sink rates for my flies and looking at maybe getting a 300 or 350ips as well.
I guess the quality of the top brands are pretty close? Not sure.
Fly lines are a bit expensive to buy and try and find out you dont really like it. [i got caught once, a few years ago I purchased a flyline for trout recommended from a salesperson in a fly shop and it was absolute crap].
Looking forward to a day casting course next month, hoping to improve the technique.
