Personally, I would choose a more conventional stock ( with a adj. cheekrest ) over the Smoke Composites style.
Especially from a tripod.
Again, just my opinion, but the SC stock looks more functional while running and gunning. The clockable butt pad would appear to fit into the shoulder better when twisting and , well... running / moving briskly.
I have never tried one like the SC... so I could be completely wrong. But a good standard stock with an adjustable cheek piece has always worked so well... I have never seen a reason to expand my "horizons".
If you buy a SC one, please let us know your thoughts.
