Ok i know this is a very old thread but I wanted to thank Yumo for the awesome review, Im going to take my chances and order the 6, I appreciate you taking the time to order both and give the update of the 8 I was gonna buy the 8 but with this review I think I'll try the 6. Do you by any chance know the cm or inches dimension to the waist? Im from Canada and returning them would be pricey >< Thanks!
