Anyone find a decent "high lift" blade replacement for a 260z?

I just reread my post and it seems my mouse moved..... My mouse is old and if my arm moves it it knocks my typing out....

I was going to add that the extra weight of the blades might cause premature wear on the spindles..... Now if the spindles are rated for that type blade and are greased regular then it's a win win.............
