Yes! I like 73. I like the font and the ball. But the location of where the guy is hitting it is behind him... Probably not a huge deal, but see what you can do. Can you make the Green a little wider so you can see the .com better ?
I'd prefer the word INSTANT with a solid color.
#75 is cool too. There is something I don't totally like with the square. Not sure what but i Think it's too ridgid. I like the pop out though of the flag! but over all not totally digging this design.
