I really don't have any idea of what to tell you about either of those species. Other than getting a guide, all I can say is that this time of year I see people trolling crank baits deep and fast on Greers Ferry for walleye. They mainly troll the channel areas but they troll faster than we do crappie fishing, like 2 - 3 mph. And I've seen people looking for the stripers schooling at dawn and dusk, usually when the wind is calm on Lake Norfork. I hope you can figure something out it's a beautiful lake to be on and catching fish would be a definite bonus.
