I use bobbers almost always in my crappie fishing from the bank. I use nothing but oval shaped bobbers that are weighted. All different sizes . I use nothing but jigs which I make myself. The only bobber I use not oval shaped is one I mentioned earlier and it is the rocket bobber, can only use 1/32 oz jig with it but works great.
Betts Billy Boy oval shaped is the brand I use I buy in bulk. I have never had a problem on hook set with any of them.
Philippians 4; 13, I can do all things through Christ who strengthens me.
