I played around with indicators on a Switch..not for me, but I was using 12 foot tapered mono leaders and a large "yarn" indicator.
This was on an 11 foot 7 weight switch with Mikes 7/8 line.
Very east to cast, supported big, heavy nymphs and turned over nice. Just found a 7 weight too heavy as I am used to 3-5's for nymphing.
Mostly snap-t's to give a bit of a sustained anchor and away they went. My mistake at first was to try and fish too far. Soon realised that a shorted cast followed by a longer drift was the order of the day. Almost like trotting with a float.
I use the same setup for dead drifting streamers
, and that works better for me.
