I am looking for a new fly line. Currently I have Cortland WF Rocket taper line on my 7wt Avid.

It works extremely well for shallow fishing but I wuld like to get my streamers a bit deeper sometimes. I'm looking for something capable of "holding" flies from 5 to 9 feet down. I was thinking about Rio stremer line but I figuire I ask some folks befure I take a plunge.

Any recommendations would be welcome. Thanks.

BTW. This is rig used mostly for warm water/still water fishing however if it's too windy I'm not squimish about using it for trout.
