OK I have an original ceramic Powerball in my TZ. I just went to the enormous trouble of sticking it on my little digital scale . . . . . 61 grams. Steel ball 78 grams (Almost 28% heavier) Incidentally, mine was a dull grey pill, but against 'net type advice I buffed the bastard about a year ago and have never looked back. I agree that TZ can be a cantankerous game but it still richly deserves its (usually) No.1 status in the world!
