Number 1 but instead of blue letters / logo make those the camo print outline them in black to denote the edge.
I like 3 & 5. Seems like it would be a good idea to have the name, logo and at least a sample of the Kamo on the shirt.
#5 and a combination of #2 & #5 (small offset KK logo over the print)
Another idea would be the full camo print shirt with with the small KK logo on a sleeve.
Are long-sleeve versions going to be offered?
