Both SSS and Stockade seem to make light/heavy benchrest type stocks. Any particular advantage to one over the other?

I kinda like the composite (less moisture sensitivity?) and internal alum skeleton of the Stockade.....but then I'm really a newbie and perhaps there is something more to consider.

The prices seem similar. My goal is accuracy and easy of use on benchrest and rear bag as I try to put together a 6PPC rifle on a Savage short action and Shilen bull (short) barrel.

Any particular advantage one way or the other you'd like to point out to me?

thanks
