Nice bucket mouth!!!!!! Big ups on a fine catch!!!
I would just stick with the 7wt. After a fly show was wrapping up a few years ago in Virginia, we were taking turns throwing the 3wt at the coke machine can drop. It was fun for that, but I don't think I would spend my money on it. Before ya buy it, think about how much you are going to fish it. If you fish a lot for bass a 6wt would be best (your 7 just fine) and bluegill are fun, but do you want to invest in them?
