A few entrants have accommodated my requests on adjustments, but they confirm the first proposal was the best. #122 makes me wonder if the three slashes are elements of an E or DNA bands....or better yet, both.
It might work to try these three slashes over/under the curves of the B rather than on the vertical. The other designs appeal to me for different reasons.
These continue to be compelling. But the tagline would have to be omitted or divided on both side of the p, otherwise it would be too small in most applications. Thanks.
