It took me a good two weeks to finally decide I was going to order the Sport aluminum model over the stainless steel model. Now I'm going back and forth on whether I should go with the Silver or Space Grey casing. I initially was 100% sold on the Space Grey with Black sport band. However, the more I have been looking at pictures and using the mix your watch website, the more I start to like the Aluminum look. It also looks to match better with a more wide variety of bands than does Space Grey. I'm almost to the point of changing my mind, but, I would have to spend an extra $50 bucks to get the Black Sport band I would want with it. I think spending five minutes in person with both versions would be enough time for me to make a firm decision. However, I'm going to have to pre-order online ahead of time, so that won't really be a possibility. Curious if anyone else is in the same boat of indecision?
