Can anyone suggest a brand and model of sinking line? I will be fishing some medium to large sized freestone streams for trout that will be no deeper than 10 feet or so with big streamers, such as madonnas, zoo cougars, Kiwi Muddlers etc. I really have no idea what I need as far as full sinking, intermediate or whether I really need it all.

Sinking line is a totally foreign territory for me. This year I have been making a concerted effort to fish big streamers for big trout but I have been doing it with normal WF-F line. I have met some success, but I am starting to really see how a sinking line might really improve the way the fly is presented and swims etc.
