Thanks ebonk for the design ideas...
1) we are really liking #63, #69... more and more, I think with a bit of modification it could look really good.
2) We like he 'i'+waves concept for #61
3) #65 the flow is definitely interesting
4) #51 is very unique not sure how it would look like if placed on the left side, we rather have a linear logo.
5) #53 looks like an interesting idea, but is not strong enough! not sure if you can tweak it abit.
