Would be curious to see #62 with a black outline around the rim around the outside edge.
Also perhaps add a thin black border around the rectangular DO IT logo in both #61 and #62 so that it "pops" a little bit more off the background.
Feel free to submit other ideas as well - as much as I like the round logos, I'm also open to other seal/emblem shapes such as a shield or rectangle.
Example:
