I'm looking to put a 7 weight line on an 11 foot rod for steelheading. I do mostly roll casting of weighted streamers/buggers, wet flies and indicators with nymphs & egg patterns in cold and very cold waters, both large and small. I want a full floating line.

Anyone have any experience using spey lines for non-spey casting? Any and all advice, including other recommendations of lines for this type of fishing will be appreciated.

Thanks
