I would worry about the balance with an Edge, so I would save the coin and go with a standard fill. I also might be tempted to skip the fluting and go with a thinner contour, again to save money. One of the first gunsmiths I worked with told me "barrels are consumables--don't spend money fluting them," so I haven't.
You are smart to go no shorter than 26"; I have had a 24" 257 WBY and been less than thrilled.
