Best thing you can do is find all the seemingly appropriate lines that Poppy (Red Shed) carries and have him send them down for you to try. It will only cost you return shipping, other than that, it's free. You've got nothing to loose. To my mind it's the greatest deal in the whole spey industry. Online opinions are nice but don't really mean that much; everyone's experience is different. The only thing that matters is what works for you.
Oh yeah, for that rod a Ballistic Vector 7/8 and Gaelforce 54 8/9 are ones to not overlook. Poppy has those as well!
I see you're a shvingger too!
