Update: Went to the fly shop today, got an indicator leader, and headed out to SC. This was my first ever time tightline nymphing, and wow. I felt like I was cheating. Within 5 minutes of practicing leading the rig through a run, I had a fish on. I only had about an hour to fish, but within that time I caught about 15 fish - and I'm sure I missed plenty. All this to say, DITCH THE INDICATOR. I cant even imagine how many fish hit my flies without it ever registering on my drop shot rig over the last couple weeks.
The rig I tied on was the 0 to 2x RIO indicator leader, about 4 feet of 4x to a uni to uni, tied a 5x dropper above this knot, tied 16 inches of 4x down to another knot, with another 5x dropper, and then about 16-18 inches down from this was where I attached my split shot. Caught pretty much all of my fish on a size 18 PT. I also was using just a 9ft 4wt, but I can definitely see the appeal of a longer, lighter rod. But im just a broke college kid, so thats somewhere down the line. Thanks for all the help and interesting insight
