Ness you only added the last sentence to "stay on topic" and not a gratuituos attempt to push this post to 6 pages.
Not sure what donuts have to do with a streamer fly rod. Except that you can use the butt section to hold the donuts😁!
But you can't do that with long johns or bavarian cream donuts. It would be too messy.
Apple fritters wouldn't work either. Bagels could hang on the butt end. Might throw off the balance of the rod and cause undo fatigue while casting and stripping streamers.
I use my 7 wt but don't fish streamers that often.
