How close is the new Eruption Pro to the Violent Eruption?  Would these be a good two ball combo (for medium to dryer) with different layouts and surfaces? 

Thanks.

I was wondering the same thing.  However, having a Violent; I am not sure it would be worth having both unless the layouts were significantly different.  EX:  One with a 5 inch pin to PAP and the other 2 inch pin to PAP.  The Violent should start up a tad sooner since it is a lower RG core.  I would think that if we were talking Mass Eruption and E-Pro, then it would make more sense to have both.  With the Violent and E-Pro, it would take a significantly different layout and surface prep to warrant having both I believe.  Having the Violent myself has really made me hesitate getting a Pro.

Violent is a nice ball, but the Pro is far better in my opinion. The cover seems stronger, i see more midlane and less hockeystick reaction. I can use mine on the fresh on anything between 38 and 43 with a very good look. The Violent is a step down, it is longer and stronger.
