Pocahontas is in a different part of the state than either Nimrod or Greeson. I don't know much about that area.
If I had my choice in April, I guess it would be Greeson. Jerry Blake and his troops have done so much habitat work there, I always have confidence I am going to catch something when I go there. Matter of fact, that's where I am headed for a four day weekend Friday.
Nimrod is an excellant choice as well. Nimrod and SlabBandit keep plenty of cover in that lake too. But, the levels are so unpredictable that I don't know if I would plan a trip that far away.
I like your signature.
