Sextracker has seen this design used several times Urb. I will use anything that works well and am not above copying and modification. I am in such illustrious company as IBM, McDonalds, Microsoft and most governments there!
What I do is not 'art' but making money. I had a previous design that did not perform so well, and have new design in the wings that hopefully will do better if I ever get time to finish it. If that does not work then I will step back to this one.
PS: if you look at Olympus-
http://olympus.kwikfire.com you will see I do some original stuff as well!
