I've got 12 of them and so far have tweaked 3/3 great "athletes" with this base. Very fast and yet they hold their line and have some toughness about them.
Now I'm kind of saving these bases for my Michigan college team, which I'm building the Rich Rod way...with speed! By the way, my best base I have is a black diamond rookie base on my Reggie Bush figure. I know people say the base color matters and I am skeptical about that, but I have found QUICK success with the green and black (in terms of speed without complete loss of strength). my experience is that you can make any base a star on your team, its just that some seem to be easier than others.
