Quoted:
Will you be bundled up in cold weather? I found the Sully stock to work well when hunting because the layers of clothes made the A2 stock unweildy and even more so, the awkward angles I'd find myself contorting to in order to shoulder it agin' a deer approaching from unexpected directions. The stubby is shorter yet so I don't know exactly. But given the choice of too short or too long, I'd take too short every time.

It all depends on the style of hunting you do.
I myself have just found the AR platform, and have settled on a short stock.
My hunting consist of still hunting deer ground and stand hunting, as mentioned above winter clothing makes longer stock firearms unwieldy. The short stock is a perfect fit for shots that are typically experience which are under 100 yds.
I went the bolt action big scope route for many years, the length, weight, site acquisition and the fact that follow up shots are slow with my 30-06 bolt, proved to be inadequate for me.
One shot one kill, is not practical for most of us in the real world, many good bucks are missed without even pulling the trigger waiting for the "perfect" shot.
It is rare for any decent buck to be walking around in broad daylight. Most good bucks stick to cover and move early or late, with daylight being an issue.
This is just MHO from an amateur, with much trail and even more error. Sorry for the length of this, hope it helps.
