G or F will probably work best for you for adjusting. The rear corner edge of the other designs may hit your wing if you're running something with low profile mounts and wanting 0° aoa as your lowest possible setting. I did lots of trimming to achieve that on the DF mounts... Ha!
The crosses look cool, but probably not doing much for structure. I built something similar for suspension once and buckled the centers. The redesign ditched the bracing in the center, leaving the larger open holes. Maybe something to consider, and I think would look even better! No harm in mocking it up to see what you think.
The thin support of the 8 may also be something to consider structurally with G. Could change font to support the center more.
