I totally agree. The viper was a demo so it was a wet weight. The 850 was defiantly wet. The 174 axys looked really clean, not sure about it. If any body is basing there buying choice by weight now a days doesn't really know much. We really wanted to weigh the viper the rest was a bonus. I know the weights aren't nasa quality but I think there close enough to say they are all in the same ballpark (except the viper).
