My thanks kind sir.
If you need any help with the tweaking, just PM me. I'll be glad to help.

Couple of hints straight up ::
1> Make use of the "seed" value when you are 'choosing' your bolt pattern. If you like the shape,
it will keep that shape and you can play with the Size and Depth to get a better look.
2> When Photoshopping the results, I suggest to try the "blur" options to get rid of the "jaggies" around joints.
