it's been a while since I have fished any of those lakes
Pin Oak is the ski boating lake. get your lake permit for it at Pin Oak lodge.
Browns and Maple are TWRA lakes.
Cub Lake,(I think they call it Cuba now) is at one of the camp sites. you have to rent their boats, you can not put your own in it. I found out the hard way about 20 yrs ago.
as far as what's biting, where to wet the hook, your guess is as good as mine.
