I'm focusing on a single color. My buddy has a plumbing business and there's virtually no application where he could use a full color logo with gradients. He uses vinyl for vehicle lettering and silk screening or embroidery for apparel or hats
I like your idea of simple. I just don't care for the round design. You are correct in what I want to do with the logo and simple would be cheaper to produce. So I am open to a different Simple LOGO.
