What is your expected horsepower output? If it's under 450 (which is easy to reach with good heads) then the Eagle cast is an option. If you expect to exceed that figure at all, ever, I would go with a better crank like a K1.

Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.
