As for stocks, I like the straight classic style best, with little or no drop at the heel. Rifle with this style are Kimber, the Remington CDL/MTN Rifle, and the best example, New Ultra Light Arms. With this style stock, if you put a cleaning rod in the barrel from the receiver end, it will barely clear the toe of the stock. Monte Carlo's can be ok, as long as the the hump is straight or angled away like the Weatherby. I like the cheek support of the monte carlo, but it seems that most of them slope toward the shooter instead of away, accentuating the felt recoil, because the rifle rises more in recoil, "slapping" your cheek. Also, with a monte carlo, if your length of pull is longer than average, sometimes the corner of the hump will dig into your cheek, especially if you use a slip on pad or get a thicker pad on the stock to compensate.
IMHO, it's just as important to have a pad on any stock design, if you have a good recoil pad, like a Decelerator, Kick-eez, or the Sims, it makes dealing with recoil that much easier.
