hi bod-
You've been busy. Thanks for the variety of options!
I like they type of "lustre" in #40, the "t" and "r" look more sophisticated, but I think "eco" from #12, 16, etc. is better (or maybe a scripty version of "eco" as an alternative?). The symbol from #12 is the most appealing in design, but positioning and size of #23, 26 & 27. I see the variety of "e's" and "l's", but none have anough presence, and I can't go too tall, so #34 wouldn't work. Perhaps another alternative to #34 with the e-l symbol on the left side and "eco" above "lustre". Don't know if that makes sense.
Thanks again!
