To carry this further, a straight stock, like the Ruger or the Remington classic, without much drop at the heel, requires the shooter to drop the head down and forward to establish contact with the comb. If not,, in order to establish contact with the comb, the butt is located too high on the shoulder and the top third may actually be above the shoulder. So, the Monte Carlo allows one to establish the comb at a comfortable height while placing the butt in full contact with the shoulder. The downside of this is that the rifle will tend to rotate upward with recoil. This causes the shooter to snivel about his bruised cheekbone. There are two remedies for this. The first, which will help somewhat, is to pitch the muzzle down a bit. The second is to man-up and embrace the pain!
People who do most of their shooting off the bench will be well served by a straight, classic-styled stock. Those who shoot a lot prone, with a low mounted scope, will be fine with a straight stock as well. Those who shoot off hand will be better served by a well designed monte carlo. Virtually all custom silhouette feature high combs but considerable drop at the heel because that works best for off-hand shooting.
Those who shoot prone but us a high mounted, big scope, will appreciate a high comb which supports the weight of their head and aligns them with the scope.
I like Monte Carlo stocks, and like the look of a well executed one; with or without a cheekpiece. I also like the look of the straight, classic stock and have rifles with both types of stock.
