I have had both of them in the past. I didn't really like either one. Both were OK, but didn't fall in love with either. The silver diamond to me, the way it was drilled, didn't get enough length and was too angular. It was too close to my pearl carbide bomb. The Pro Pruple, I liked the roll, but it left too many 10 pins. I could never get it to carry the ten, no matter what angle. The Buzzsaws that I love. The Super Carbibe, great for heavy, nice early roll with a good arc. and My favorite, the Cherry Bomb. Love it. Didn't think I could like any SAW more than my Pearl Carbide Bomb, but I now have one to take its place.
