Hello May I ask which stock you went with sir?Thanks. I found the info I was looking for. Still undecided.
ThanksI went carbon. But not because I know it is better, but because it is precived as being better and I've not compromised on any other parts. Sad. I may pick up the same stock in fiberglass for a budget build in the same cartridge. If so I will post my comparison. Sorry I can't make a first hand comparison for you. That is what I was looking for. Someone like Alex Wheeler could probably address the true differences, like recoil impulse, rigidity, strength etc.
