Poppers are always good to have on hand. if nothing else its fun to make them pop and hop, makes you feel like you are doing something constructive

I'd say bring the kitchen sink. my personal experience in OK farm ponds has been that yellow is a great color, no matter what the pattern. I suppose that chartreuse would work well also.

There are so many beautiful little rivers in SE Oklahoma, Google that up and also check with the Oklahoma Wildlife Department.

There may still be some sand bass in the rivers when you get there, hard to tell this far in advance.
