#11 - Like the RF design but would like to see the "root and Foundry" more like #3.
In general the layout of #3 I like the best.
#6 RF is too fancy. Like more rugged RF. like #8, #3, #11
Favorites so far are #8, #4, #11, #3.
#3 - could you incorporate F with the R. There is another company that uses just R for symbol and I don't want to send mixed messages.
