Good morning,
              In my opinion the blue vibe is going to be above that low end bowling ball like the tundra or the cyclone with a controlled backend reaction.  As long as you’re seeing the best reaction on and off the recommended lane condition I believe you will be fine. 

Just to make it sweet once you start seeing how it goes through the pins you’re going to be happy with your purchase.  It can hit like a tank.

I have the blue and once there is defined friction downlane, I get this this out and strikes for days.

I liked the original cobalt just a bit better, but you cant beat that vibe core .  Great read ball on flatter patterns.  I can get mine to hit from multiple angles.   When it labors or doesn't carry I can udually make a small move and step up to something stronger.  On the other end they have to get pretty toasty for me to lose my look from deep inside.
