I would start with something that's already linebred..staying from scratch would take to long for me.
Not necessarily.
Depends on what your looking to put into your line and what you already have available.
I'm hoping it won't take more than a couple generations of hard culling to get the stopping power in looking for.
I'm not in any hurry anyway.

I like a whole lot of the basic traits I'm seeing in my pups right now (handle, personality - as far as their general attitude) build/color. Their individual hunting attributes are still developing and ill have to wait and see how they "finish" out but I'm very pleased in what I'm seeing so far.
