This is by far my "Ball of the year" I have mine drilled with my favorite drilling , which is pin above the fingers, CG slightly swung. Since I got this ball earlier in the season. I have thrown five 300 games, two 8-- series, and two 299 games. I have used this ball on league shots, sport shots, oily lane conditions, and burnt out lane conditions. It seems to find the pocket on almost anything! Also have had people in my Thursday league drill this up with great success. A Lefty in my league shot 800 out of the box with it! Drilled one for a guy averaging 173. He has had his new hi game of 278 and also threw his hi series of 673! He is convinced a 700 is right around the corner! I plan on this being the center piece of my USBC Nationals arsenal as well.

My mass eruption and my vow are probably my 2 favorite bowling balls in my arsenal right now. My Arsenal is 15 balls strong and all columbia 300. They are all very impressive bowling balls. However , the mass and the vow are just sick. 2 of the most versatile bowling balls out there. I can throw either of these on anything except the extremes. The mass is a very hard hitting ball , and carry is great. I have a 2nd mass , but I'm yet to drill it up. I may drill it up later today. Columbia 300 just keeps hitting grand slams with their last 5 releases.
