If you have a 6wt, I'd go with a 4wt...A fast 6wt should be OK for smallmouth fishing with medium sized flies (size 2 sneaky petes, and subsurface stuff 3-4" range as long as they arent too heavy) and casts out to 50'-60' or so, but youll want a 7 or 8wt for the bigger, heavier stuff, longer casts, and sinking lines. The Sage Smallmouth rod would be a great choice for a heavier setup in the $250 range and it comes with a fly line(no reel)...Its only 8' long, but its a real cannon. Grey's makes some nice mid priced offerings too. Stop by Tommy's or FC, cast a few, and see what you like best. Cheers.
