I dont know much about clubs and stuff, but I've been to guntersville twice this year. Guntersville is a monster! Lots of waters and grass, but it loaded with fish.
In one morning we found school of stripes and caught over 50 fish in 20 minutes between 4 of us in two boats.
As the day progress on the same very day we found 7 bass in less then 20 minutes.
Also hooked two 5+ fish 5 minutes apart.
Guntersville can be slow, but 15 minutes later there could be a feeding frenzy then you'll have to grind it out again.
I also must add the area like boaz, albertsville, guntersville, scottsboro, etc. Are really nice cozy small town you'll learn to like it.
Hope that was some help. I do know is there a lot of local tournaments every weekend so your bettr off working on weekend and fish on week days.
My cousin belongs to a club in Tuscaloosa (two hours away) and his club host tournaments on guntersville once or twice a year. So you'll see clubs from all over the area visiting guntersville.
Hope that was the information you was looking for, anymore question PM me.
