Thank you all for your thoughts, I'm still chewing it over...
I know I could just go for the black and, of course, it would still be the same bike, BUT this is a big ol' investment and my "bike for life" so it has to be perfect. The delivery time is now apparently early September, so not too bad, and everyone at SJSC has continued to be very helpful.
Maybe I'll spend some time saving up and treat myself to some bling parts when the time comes: any recommendations? :-)
