The 7mm STW is definitely right up your alley.
The .264wm is a great choice as well.
To push either the 7mm Faster than the STW can do, or the 6.5 faster than the .264wm will you are going to be getting into calibers that are very much going to eat barrels for you.
If barrel life simply isn't an issue then either a 6.5x300wm or 6.5STW would be the ultimate .264/6.5's for you.
I personally love the 7mm STW and .264wm and see no reason to push either round any faster than those two calibers do.
26-28" will get you peak performance from the .264wm and 29-30" will get you the most out of the 7mm STW.
