Tony,
Indeed a have a lot of experience with those stocks, but I tend to shoot the lowest possible profile. Pippin and others cannot compete against, at least for my shooting style, with the lower profile ones. As much as I like the Pippin profile they all have been replaced by our (Ricardo and myself) design. A lower profile one, lightly made, but with CF laminations to maintain stiffness.
They are just more precise, or should I say "forgiving"?...
Physics don't lie, the closer the GC to the recoil line, the better. You'll have less recoil upwards jump, and much less roll. Less roll will mean less front pads pressure, so better movement flow. This can be explained by vector power directions and lever effect. The higher the stock the more leverage you'll get. That's another reason I preach the least possible weight on top of the action.
Looking at Boyer's stock picture, I think you can go even lower, not only on butt area, but also at the front. Secret is getting a lower profile, while maintaining the same stiffness. Carbon fibre helps a lot here.
Finally a warning word using CF... it should be well damped against vibrations. Balsa as core material is great, as well as some polyurethane foam. With foam you should choose density according to desired weight.
Interesting enough, the harder the wood, the less damping properties. Also, try to avoid wood used for musical instruments, like Spruce, Mahogany, Ziricote and others. If some of these woods are going to be chosen (beauty for exemple) laminate them with cross grained planes.
