First, welcome aboard here.

To answer your question about the Violent Eruption first, you could look at the Mass Eruption as a compliment.  Same core, hybrid New Era cover instead of the New Era pearl on the Violent.  You'll get a slightly earlier read in the mids but won't get the overreaction you can find sometimes with pearl covers on the back.  If you want a solid cover, the Disruption is the best choice.  Also, the same core as the Eruption series, and uses a solid version of the New Era cover.  at would make a great 1-2 combo.  Use the Mass Eruption or Disruption when you have a little more volume up front and as the lane transitions, switch to the Violent Eruption.

As for long patterns, I'm surprised that the World Beater isn't getting the job done, because it was one of the strongest balls that Columbia 300 offered just a few years ago.    If you haven't had a resurface/bake done on the ball, you may want to give that a shot first as that cover does soak up oil. 

If you do go with a new ball, the Enigma is one option and it would work.  However, you may find the Antics could fit your game better.  It's a strong solid cover but tends to be a little cleaner up front while giving a strong move in back.  It also works well when polished.

tommy,

As for Distruption and Mass Eruption I know that these are great balls, but my coach encourages me to try Storm, so I thought that the old Hyroad coulb be the one to go with my violent eruption?

As for world beater, I know that it is a strong ball but maybe my drilling is not to strong (50x3 1/2x 30), maybe my revs are not so high, maybe my pap changed, because this ball was drilled when a was novice bowler, but in general I want a little more hook:) I'll look at the antics but voice inside me tells that I want enigma more:) So in general I want very strong ball which compliments heavy conditions and my not so high revs:) Are you saying that Antics would be stronger than enigma on heavy oil conditions?

I would say Enigma all day for a heavy oil ball.. I to am a speed dominate player and the Enigma seems to always find a way to hook for me.
And the Disruption is great ball for those that liked the Violent.. Little cleaner through the front and a little more on the back end.. Great stuff!

For the heavy oil I would go with the Enigma, ball has not done myself any wrong with that use.  My favorite for heavy oil is a pin down with a low X hole and sanded to 800 grit, only comes out for real heavy shots.  Another ball I would look into is the Smackdown.  If you want a subsititute for the Violent, why not just get another Violent and drill it a little different?
