I ordered with 21 ounce weight. With a good tight rack it is like a explosion when the cue ball hits. I think it is the extra hard Bakelite { early plastic, very hard tip }. Great balance on STICK. Spreading the balls across the table and sinking several balls on half my breaks every time! If this STICK was any heavier I think I would break the cue ball in half. GREATEST IMPROVEMENT IN BREAKING IN ALL MY MANY YEARS OF PLAYING! Several friends said I am breaking now like I am shooting a Canon ball instead of a cue ball. This stick is a must if you play! F.Y.I. Wooden rack always gives you the best and the tightest rack every time. Many pool halls and bars now no longer use wooden racks? I bought my own here for a few bucks when I purchased this STICK. Just shows even a old dog can learn after all these years!
