Re: What is the secret to casting with an indicator
Bingo -- water haul or "slingshot" casting is the best in my experience.
Particularly if you're using a light rod (<3 weight) and heavy flies, or split shot. I've fished a few rigs that were so heavy you honestly couldn't cast them if you wanted to, even with a good haul.
Water hauling works great though and sometimes you need the weight to get deep.
I also use water hauling in really windy conditions for long casts (like 50-60') on some of the big rivers around here. It makes the experience more relaxing.
