It's OK...I just see 'neck' and 'dive' in threads and it get's my heckles up a bit!  
 
The benefits of playing Thunderbirds (lack of body weight, slender neck, that tone, the uber cool shape, the magical ability of it being able to transform me into a lithe 20-something), by far outweighs any issue with diving of the neck.  Most people who talk about neck dive probably haven't even touched a TB.  It saddens me.
