Default Centipede -- the next generation antenna

I had a bit of time and I made a comparison between SBGH and "Centipede."
Both models were brought to a common denomiantor and the picture snaps were made with the same settings. This is not an "experimental models." I have built "Centipede" and it works -- so I think it deserves its own thread for people to know. I am sure that "Centipede" could be much improved.
It would be nice if this comparison composite result wouldn't be burried in the hundreds of posts of the "Area 51" becuse the results are speaking pretty clearly. The file used for comparison is listed below the composite picture for those who what to try doing this task.

I would like to thank all the people who helped me in honing this antenna into a robust workhorse.

Thanks for reading.

Input deck:
