Don't forget Greeener came up with the Rational Stock back in the day. A hogback that did the same thing as a Monte Carlo. Fashion plays a much larger part than we want to admit. That and the changes of the human body as it changes and the habits and form of a shooter changes. Too high and too long are harder to shoot than short and too much drop. Add into that that an veteran shooter can adapt to many slight changes in dimension But a stock that "fits" on a day or for a season can make magic happen.
