fly fishing for smallmouth bass

Fly fishing issue fairly easy ten points?
In summer, Im going on a fishing trip to the shenondoah and the Potomac River I need to know what type of Fly Fishing Line I need to take smallmouth bass and trout so I need a light line for trout? approval of other responses I heard I'm not giving a description of fishing here im pretty good for small mouth and large mouth under the serpentine also chat with the nymphs and never again?
OK, so this is what I face this situation. September weight rod, 8 or 9 feet. A reel with extra spool, making sure who is responsible for seven lines of weight. Coil weight to seven the coil and the other with five weight for leaders and tippets the weight of the corresponding row. When the fish using small weights seven years, when you can fish trout reel change with the weight of five. Good luck
