The rod is a 9' 6wt, with 8lb test tippet.
I'd caught a big bluegill and when I had the bluegill halfway to me this bass attacked it, spit it out and came back and took it again. I set the hook like you normally would for a bass and the hook came out of the bluegill and into the bass's lip. That's the third or fourth time that's happened in the past year or so.
Best I can tell is it's 21" long and 21" girth, based on the known lengths in the photo and how thick I remember it being. From the formula this would be an 8.16lb bass. Or so it would appear to me, how about to you?
