Laminated stocks, provided they are wood laminate, are considerably heavier than other stocks typically available. Some folks hunt with them but they find their primary use in target shooting. A well made laminate stock does warp less readily than non-stabilized, solid wood. I say well made as one can laminate wood with the grain all in one direction; this setup can produce warp in and of itself. A stabilized solid wood stock will typically not warp in humidity, but they are just as heavy, if not heavier, than wood laminate . . . and more expensive.
Though wood laminate is more rigid than some of the synthetics, the high-end Fiberglass Stocks (they are actually laminate, just in multiple directions) are still king in terms of rigidity. Fiberglass is typically lighter than wood laminate.
I suppose one could make a carbon fiber laminate stock . . . lightweight, super rigid, and no warp. It might cost more than your rifle, though.
