I have a predator vantage that I'd like to take down to 12.5. I've seen quite a few older 314s around 12.0 or less... I know it will void the warranty and I certainly won't be breaking with it. I like the stiffness of the vantage over the 314-3 and just want to feather the last 6 inches or so down to make what I think will be the ideal shaft for my playing style. Anyone have any experience? Thank-you
