Hello all. I'm considering a build, and was wondering if anyone knows how much (roughly) a body and neck should weigh in order to keep it as light as possible without neck dive. Would 5lbs for an unloaded body be considered heavy, average or light? How much does an average neck weigh? Ideally I would like to keep it under 9lbs. I did a search, but nothing came up. Any info would be greatly appreciated. Also, is there a formula or rule of thumb that would state what the ratio of body to neck weight would be optimal?
