Maybe check out a short sink tip instead of a full sink or a grain line with a 30 foot head. It might enable you to get down with having to deal with the headaches associated with sinking lines from shore.
Of course, not many companies make such a line.
I think only Teeny does. We don't carry this line (but I can special order it) as it would almost never sell (I've tried) but I'm thinking of trying again. I really feel it's perfect for a lot of situations for shore anglers who need to get down but don't want the wrestling match of a full sink or 30 foot head grain line.
