better to have them on the neck, which isn't judged, instead of the back, which is judged. 
Wrong again Neo , the neck is judged you'd know this if you knew the first thing about competitive bodybuilding

I'll continue to teach , you continue to learn.
When assessing a competitor’s physique, a judge should follow a
routine procedure which will allow a comprehensive assessment of
the physique as a whole. During the comparisons of the
compulsory poses, the judge should first look at the primary
muscle group being displayed. The judge should then survey the
whole physique, starting from the head, and looking at every part
of the physique in a downward sequence, beginning with general
impressions, and looking for muscular bulk, balanced
development, muscular density and definition. The downward
survey should take in the head,
neck, shoulders, chest, all of the
arm muscles, front of the trunk for pectorals, pec-delt tie-in,
abdominals, waist, thighs, legs, calves and feet. The same
procedure for back poses will also take in the upper and lower
trapezius, teres and infraspinatus, erector spinae, the gluteus
group, the leg biceps group at the back of the thighs, calves, and
feet. A detailed assessment of the various muscle groups should
be made during the comparisons, at which time it helps the judge
to compare muscle shape, density, and definition while still
bearing in mind the competitor’s overall balanced development.
The comparisons of the compulsory poses cannot be overemphasized
as these comparisons will help the judge to decide
which competitor has the superior physique from the standpoint of
muscular bulk, balanced development, muscular density and
definition.
