That looks good! Way better with the bead rolling.
When doing a series of tabs like that, I like to cut them all out of one continuous piece of metal and then stitch weld it on the tube. It's way easier to let the computer define the tab spacing and being one piece, they will all be more or less coplanar. Once the long tab is welded on, I use a transfer punch to knock a dimple into the sheet metal for the holes.
