I like the idea of the "stacked" words ('spunk' on top of 'worthy') in keeping with the original logo. In particular
#5 with the connected letters is pretty cool, but would like to see more chunky fonts so it really pops out. The logo is probably going to be put on top of the photo of the waves crashing (see the banner uploaded) so it'll need to really stand out on top of that.
Also, the ".com" could be in a smaller font size-- maybe 50% or smaller of the main text? It could even be turned 90 degrees CCW so it stands vertically against the 'y' in 'worthy'.
Thanks again.
