Although I like the white version of phrog's design a lot, I'm a little partial to the standard window sticker that sbpilot made.
BTW, any reason you can't get two designs made? If there's enough demand having a choice between the top two vote-getters might work.
My own $0.02 on this subject. Having been a former Battalion MCCS officer, relying on demand and people saying "yeah, I'll buy X number of stickers" and then not following through, gives the potential for someone to be left holding the bag. I think that it should work this way:
We decide on ONE design for now, and figure out who's going to pony up for the initial purchase, or collect money in advance.
Do an LRIP of those stickers, and see how quickly (or slowly) they sell.
Sell them for a small proft, and maintain an "Airwarriors Geedunk Fund".
If they sell well, and there was enough demand for a second design, use the "Airwarriors Geedunk Fund" to purchase a second lot of both designs.
Sell those for a profit, and then look towards Polo Shirts, T-Shirts, Coffee Mugs, Pens, Keychains, USB Thumb Drives, Beer Coozies, etc...
If they don't sell well during the LRIP, then no-one is left with a gaping hole in the finances and a shitload of stickers. Case in point: upon "demand" and suggestions, I purchased 1500 stickers out of pocket for the Battalion. At the end of the day (when I went on terminal), I was still $485 in the hole and had something like 900 stickers left over. I left the stickers at the Battalion, and drained the $400 that was in the Battalion's MCCS funds (per the CO's/OpsO's guidance), and still walked away $85 in the hole. I don't want that to happen here.
