GSP’s need to run, and Range (don’t hunt close)
V’s (at least mine) are thin skinned (can’t take REALLY Northern Cold), but hunt well, and tend not to bark.
Basically if you plan to keep it in the house the V’s are better, because a GSP will drive your wife nutz.
GSP’s are better being outside dogs in my opinion.
Another caution about V’s, they are not as genetically solid as the GSP, they can have mind issues (noises put them under the bed), because of the massive in breading that occured when the brought the bred back from the edge.
