That line won't work very well. You'll have to choose a Spey line. I would read up on different lines and decide the one that best suit your needs. Some anglers, however, feel long-belly lines are the hardest to learn to cast, but with those lines you won't have to retrieve line after each cast.
If, by chance, you want to use a traditional fly line you'll have to go up three or four weights.
