Clarifying here, it wasn't the flies that caught the 32+" redfish and 25+" black drum.
It was the mile wade across Fence Lake each of those two days, seeing each fish feeding from a half-mile away and,
especially, making multiple stealthy presentations to both fish who each decided from my activity that I was a heron.
(Sight-fished other smaller fish on the stalks to find these.)
I know guys who, with the same effort, would catch those fish on a black nickel Johnson silver minnow.
Likewise, the schooling reds was all about seeing it coming, lining up at the right structure (the shoal the fish were using), and patiently waiting for it to get to us - gave us time to tie on our baitfish flies.
40 flounder? Even in flagstone creek bass fishing, a whistler pattern variation is the perfect bottom-bouncing fly, keeling hook up and brushing up a good mud-ball.
With a good bottom bouncing technique, any gamefish will pick up the fly when it's sitting still - rainbows, big bass, stripers and of course stringers of white bass.
The 40 flounder came from the boat ride to see the surf at Cedar Bayou, a good tide (dues paid-up luck), and suffering the elements - could have caught more, but it was cold and long boat ride to get back to Goose Island.
Same technique caught 50 white bass on consecutive casts one day - with particularly good timing, the lake level forming a perfect pinch point, and every white bass in the lake wanting to get by me. It was a weekday and everyone else out that day didn't make the 3-mile hike to the pinch-point, but were fishing the pools upriver.
It's also the technique that catches white bass when no one else is, and other's don't even know they're still in the river.
Aside from improving your odds of catching a 4-y-o male, nicest thing about fishing harems late in the white bass spawn is all the crowds have gone home, thinking it's all over.
