I generally like Echo rods, but in this case I'd sooner spend the same amount and get a 2nd rod as well-
Now you can convert your 3 weight 8 foot BVK fly rod (by TFO) to a 5pc, 10 foot fly rod for High Sticking Nymphs and Longer Casts.
It's simple, just remove the butt section on your 3 weight 8 foot BVK series fly rod and add the 2 piece conversion kit .. and now you have itů A 5 piece 10 foot fly rod that will shoot line farther and help you cover more water while nymphing.
8' 3wt- $230, Conversion kit- $100
