It also depends on what a person classifys as a halter horse,one or 2 halter horse names in the pedigree does not mean halter horse
.There is also what are considered non halter lines of horses that are more halter like in their looks than you'd expect. I would just judge the horse individually
. They certainly all can't be painted with the same brush.
My Superior halter mare has no typical halter pedigree,no Impressive lines & has great bone / feet size.
