Friends;

I do not know what size your bass are but I use a 9 wt setup and throw a 2/0 clouser the same one I head out for snook or speckle trout.

I have caught bass on smaller hooks but when I am going for bass the smallest hook I use is 2/0.
The biggest bass so far on the fly rod is 10lb 4oz this fish was released to make big babies.

I keep all color of the clousers in my box, I tend to fish stained water so bright colors are my favorites.

If you are fishing for smaller bass then smaller hooks would be acceptable.

Keep fishing and catching. Also Jim Hatch has some killer bass flys that he makes for top water. Nothing beats catching a big bass on top water. Well maybe a new boat but that would be all...

Go get em
