Looking for advice on a (probably intermediate) shooting line that would work well with a full intermediate head on a light (5wt, 13') spey swinging for shad. I have a 35# gripshooter and was thinking that this might as well be one as it probably would get sunk by the head. I guess regular mono might be some people's suggestion. I also have a spool of 25# Opst lazer. Maybe none of these is technically intermediate, but maybe just a good? Feel free to convince me I should use a floating running line if you feel strongly about it - with the int head and sink tips I would guess that thing might be able to dredge Neptune's briny deep all by itself. The only experience I have is messing around with an int head wullf ambush.
