My take on the toe line discussion is every design is a trade off. Time to design a stock with an adjustable toe line, maybe!
The customer/commenter focus for the RS has been on the negative comb, probably because it's the most visible departure from common stock lines.
In shooting the RS back to back with other decent stocks (Grayboe Phoenix, Bastion, modded factory) what actually stands out the most to me in practice is the straight-to-the-rear tracking on the bags. That comes from the flat foreend and the flat toe line.
I don't think folks appreciate a few things enough about that flat toe:
1) How much of your reticle rise in follow-through is actually due to a sloping toe sliding backwards down a bag - not "recoil"
2) How nice it is to be able to make elevation adjustments by squeezing ANYWHERE on the stock your off hand might end up due to positional considerations
3) How much more control you have when YOU get to decide where your off-hand is vs needing to place it where the target elevation matches the slope of the toe
4) How easy (and professionally common) it is to make elevation adjustments by squeezing a rear bag
While I'm still building rifles on Bastions, that's driven by factors other than a belief in any advantage whatsoever of a sloped toe line.
