I like your new entries
#68 and
#69.
#70 came in after my latest re-ranking.
Swooshes are overdone in the post-Nike era but somehow they work really nicely in
#69 with the suggestion of a "W" as well as the suggestion of partners.
I am a geneticist by training so the "DNA" symbol suggested in
#68 is attractive especially since you also make it suggest a "W" - it can also be read as an M and a W which are my initials (MW) so that is appealing. The two tones of blue look fine but the grey in the middle doesn't really appeal to me. Please try some other colors. Green has been popular and looks pretty good but you might try some others that look good too.
By the way, thanks for hanging in there after pitching in early to try my lame suggestions with the R - you now have a very strong contender.
