Are you considering getting a do-it-yourself stock, which is 90% inletted or would you go to Wenig's in Missouri to be fitted and have them make the stock (and forend?)?
The New American has an offset comb, which many shooters find helpful because it often eliminate the need to tilt the head toward the stock to horizontally align the eye with the rib.
For that reason, shooters can shoot facing targets more directly, which is good because it does not hamper swings in the direction opposite of the gun mount - to the left for a right-handed shooter. That is often necessary when shooters shoot their shotguns like a rifle, with the shoulders nearly aligned with the direction of the shot. Shooting like that invites arm-swinging the gun rather than swinging using upper-body rotation at the waist and hips, powered by the legs to move the gun laterally.
