Why would this be looking for trouble? For the people on this forum that I respect their comments (both SL and WL people), they know I am asking an honest layman's question. Everyone else, well, I know how to ignore unuseful information.
I can relate more to the WL. A dog with that purpose makes more sense to me rather than a SL. Not to say SL are negative; I just have a harder time relating.
There are more people like me who would not know a SL / WL from a hole in the ground; at least at the visual level. From what I have learned so far, if I intended to get another GSD in 5 - 7 years, I better start researching so I make my own decision without fully relying on others to "tell me" what dog to get.
Anyone can feed me a line. At this point, other than asking around, I will not know the difference. Again, there are a lot of people like me.
Once I see a dog in action, yes, I have learned enough to tell the difference. From a photo, no, I still do not quite "get" what I am looking for.
