If you were to allow me a single bait for the rest of my life, the tube would be it. I think the versatility is VERY underrated. There are a myriad of retrieves for a texas rigged tube.
Swimming, hopping, & yo-yo retrieves mimick a bait fish... dragging & hopping retrieves can mimick crawfish... throw one on erie to mimick goby... or peg the sinker, & you can pitch and flip these things into the gnarliest messes you will find. Weightless, dropshots, Carolina rigs, you name it!
If I'm fishing, I have a t-rig tube on one of my rods. It's my confidence bait. Throw it anywhere you would a worm, or a jig!
Green pumpkin is my favorite flavor. I use it 99% of the time. When the water is super muddy, I may switch to black.
