Center Male one may notice the patterning on the back is quite consistent as far as width

& patterning is more fine overall than is case for LESC

 

Head shape generally...keeping in mind variance in individuals , as well as postures and 'wetting' after diving etc.

 

GRSC head length is proportional to height

GRSC usually has and/or giving comparative appearance of an overall (larger) rounded head

GRSC - highest point of head is above or in front of the eye..impression is slopes toward back

(and at times even gives impression of a bit of a flat spot,top of head)
