Our hexagenia patterns come from Pacific fly group. Their hexagenia nymph, Cripple-hex, BMAR Ultimate Hex and their Hex spinner. We also use stimulators with a yellow belly. As for if you will get dry fly action, I don't know. Like I said before, even when the hatch is good, getting regular rises is ify here, but not completely unheard of either with this particular hatch. If the hatch is fading earlier this year as the last few days have, then it will be even tougher. If it comes back, then it may be possible. They come out after 6:30pm when they come do make an appearance. That being said, all the normal big flies bounced along the bottom are working. This has also been a big year for the prince nymph on the Eleven Point (size 12 has done well for me).
