How much dah are you looking for? SKB gave you a good approximation of how much a dah change will make to the dac. If you dac is too low after bend for dah removing the cast off will help. I had a stock that was bent down and had cast off bent but the cast off ended up being too much. Had to have it rebent to reduce the cast off. Good wood is amazing to see how much it will bend in the hands of a good stock man.
Another thing to look at is where the pitch will be after bending. As I get older I notice pitch more than I use to notice it. Wrong pitch gives me a little face slap at the dac. The best way to know is to use a pattern plate after bending to see if your poi is correct as well as the stock fitting you properly.
