Jesse,
It's good to see another fly fishing enthusiast in the area. Chance has given you some good info and you should hook up with him as soon as possible. I have the heavy rod ready, but I haven't had the opportunity to land a striper on it yet. Unfortunately, we're having another one of those "Wet" years where our favorite fishing rivers are blown out. As Chance mentioned, the Lower Illinois (when the water level drops) will be a good river for you to visit that is only about an hour away. It's mostly fishing for Rainbows and small Browns (all stockers) and sometimes you'll get the opportunity to fish for Whites and Striper.
Until the water gets right, don't rule out tying up some small poppers and foam bugs and buggers to do a little pond hopping chasing the Bluegill and Bass. You might find yourself having hours of fun, some evening, in some of the neighborhood and city ponds around Tulsa. I live in Owasso and have been having a blast, at the pond by Home Depot, catching BlueGill, Bass and other sunfish.
Once the water gets right on TaneyCoMo, you really need to get up there and try some night fishing for the Big Rainbows and Browns. Your 6wt may be too small.
I've never fished the Current, but Chance has and he can tell you all about that as well as Crane Creek and Roaring River. Not to mention, in Oklahoma, we also have the Lower Mountain Fork river for another trout fix.
Good Luck and Tight Lines,
Phil
