Just broke the ball links off my blade mounts today and was wondering if the aluminum upgrades would be worth the extra $$. Im thinking of upgrading to all aluminum (at least all thats available), but was wondering if there would be a change in performance. I could care less about the "bling" factor, but if I could get more manuverability and/or more durability, it might be worth it. Another thing I am worried about is something else breaking because the aluminum parts dont give. Any advise?
