Hi
I'm a young fisherman and when fishing some small light buzzers I find indicators great fun as it's intresting to watch the fish dragging your flies either away from you or towards you. But if I am fishing some larger heavier flies, I find that casting is too heavy and clumbsy and it's not worth having to try and deal with the tangles that are caused by some of the fluffier strike indicators.
But still, their good fun.
