I've been invited down to fly fish the Roanoke river this spring for stripers. We will be fishing from a boat and I was told that we will need a line that will sink at about 12" per second with the depth of river 15'. That being said I'm trying to figure out how to set up my 9 weight without having to buy another line. I have a old Stu apte 9 wt. multi tip fly line that I can use and would like some suggestions on what type of 30' head would work the best and not bust the bank (it's only going to be a 1 day trip) Thanks.
