I kinda liked the scrolls, they looked classy. And though the idea of a giant gear is cool, the ones shown are a tad too busy for me. I was thinking to play on BGs idea of moving the circle scroll a bit outword towards the sides, and keeping it the same size or close to the same size, And as an option, make it a gear shaped similar to the paradice shaped Inlay, but just the outline?
I think I'd have to see it first, but if all ele fails, the circle tire tread might be just fine. Or as stated just to leave it out. Keep it simple, subtle.
I like the chains , however, im using a bad Internet connection on my iPad (while on a beach) and it's not ideal to see detail on any of the recent design mocks.
. Can't really complain about the bach tho...
