Thanks for the clarification, Gary. I just took a close look at my brush and there's definitely no glue bump. I can't say that none of the FS brushes will have it, though. Who knows what kind of quality control they have there? Maybe I just got lucky!
All I know is I really like the brush and it quickly made it's way into my rotation.
