I think in order to help with the segmentation, you really need to twist the **** out of the antron. That really seems to help give that really nice segmented look. I even give it a wrap, twist, wrap, twist, wrap, twist, etc. Really seems to do the job. Also, I tied in some dun (or use whatever color you wish) ostrich herl and palmered it forward between the antron segments after I had tied the antron off. It really helps with the segmentation and adds to the overall 'bugginess'.
