Alfa Maybe just replace the A with the hourglass and lose the triangle

Bravo Or maybe just the sand from the bottom half of the hour glass on the verge of being filled? It would be simple and subtle!

Alfa Even better!

Charlie Yeah just have the hourglass

Delta Thanks for the feedback guys I appreciate it.

Echo As bravo suggested. I think it would be more subtle with a stylised pile of sand with some grains fallin on it. Just implying the sands of time but not so obvious.
