In posts #25 and #26, the phrases "real fishing distances" / "fishing distance" were used. If angler 1 belly crawls at the letort to get off a 6' cast at a fish they stalked for an hour vs an angler near Trenton double hauling it 80' to cover a pool during the shad run..... With almost 75' of difference, which is a "real fishing distance"? Just because a person doesn't get the opportunity to fish 60' or further away doesn't eliminate it from being a "real fishing distance". Sometimes you can not close the distance due to water depth / speed, sometimes making a few steps will spook the fish or sometimes you just say "wonder if I can get that fish from here".
Don't get me wrong, trying to fish across 4 currents isn't anyone's first choice but it's going to catch more fish than not taking a cast. If an angler is deadly at 58', I like the chance of them being deadly at 15'. Reverse that and I'm not so confident the accuracy will transfer.
Good mechanics are easy to pick up. General knowledge of fly casting... also easily accessible. No angler can ever be hurt by improving on those 2 things.
The thing that troubles most anglers in my experience is line control. That's the thing that takes the most work IMHO.
