That is how you catch fish, trap fur bearers, kill deer,,and about all success in the outdoors depends on those there functions. Equipment comes in far below that. Hunt till you find the fish,,,can't catch what isnt there,,reading water is the best knowledge you can have. I can hold my own with most on a stream but my catch rate drops in a lake. But I spend 80 percent of my time probably fishing streams. So, I know that type of water by instinct and training.
Set up...you just dont walk up and shoot a gobbler,,,,and you just dont stumble over thur the stream and catch fish. Stealth, break your outline, put all the 'edges' in your favor BEFORE you even consider casting.
Presentation,,,important. Don't fine tune the other then put out a cast that is train wreck,,,,one that goes in a bush and you have to make more motion than a circus getting out of that mess. Or undue rod waving, or two low and too hard of a cast (esp dry flies) that smacks your dry on the water till it makes ripples. Pause, get in the grove mentally, then show them your cards.
Those three things aren't magic,,mostly,, they will come by just not being in too big of a hurry to cast that you forget to 'think.'
Gear,,,I love gear but I'm average,,I'm not loaded with dollars. I try to have decent gear, I'll ponder on a rod for months before I pull the trigger on it. I do not have the best rods, but I have good rods. My other gear,,wading, tackle, sunglasses,,etc,,,are decent things,,,buit not the best. Hell, I use a cut hickory staff I get from out back of the house for my 'wading staff.'
Now here is why gear comes forth,,,at least down to forth,,,,you can have all the best gear,,screw up one or more of the first three,,,and you will only have hiked in to cool off in the stream. Even 5 year olds with a push button Zebco can catch fish if they have someone to help them somewhat execute the first three steps.
And Mojo...if you get attacked by a herd of long legged wimmen you mentioned,,,get in contact with me, I'll do my best to fight some of'em off for ya,,even if it means getting physical with them. No need to thank me, I'm just that kinda guy...
