I started with the 3000 series aviators, a 4000, and then the GW1000 series. There are features that I like from each. I finally tried on a GPW1000RAF model but something about it just didn't click, might have been the size. I also live in Japan and the GPS syncing feature doesn't seem like a need to have, am I missing something? Just curious about those who have the GPW and their thoughts. Thanks!
