I use this pattern. So it's definitely not a perfect sphere. I also add a bead. The fish didn't seem to mind at all. Plus you can crank them out fast. I used about 75 of these last weekend, losing many to the rocks and many to the fish. Also, I am now a big fan of Sabre's hooks. The globug salmon/steelhead model in 2X heavy performed flawlessly.

When I'm tying other globugs, I find a tighter pull upward as I snip the yarn yields the best sphere. But it still requires some teasing out. For tiny eggs, i tie an Antron veiled egg.
