Love fishing for summer runs with a #2 or sometimes #1 Vibrax with a split shot. I always replace the treble with a siwash due to snagging the trebles on the bottom (thats where you want to be ticking the bottom once in a while like drift fishing) and the damage the trebles do to smolts and trout you will catch. I have found that once you hook a fish they stay on just as well as with a treble with a lot less damage if you are going to release them.
