Stronger/smarter/faster than a lab??? I'm not really buying that assertion.....
I prefer labs (too) for a variety of reasons, but get bombs thrown every time I dare mention it on this forum.
For pen-raised or early season birds that hold for a point, I'm sure that the pointers on this forum are all world-beaters. HOWEVER, the smart (and wild) late-season birds I hunt simply won't stand still and hold for the pointers I've hunted with. They are too busy RUNNING and FLUSHING.
Perhaps the best reason for a lab under bad conditions is that they can take the COLD temps AND be able to navigate through thick cover that the smaller/softer dogs can't hack.
The OP requested some opinions on why we like labs over other breeds, and these factors are just that. And, they are free and worth every penny.......
