I have not seen very much information online about the TNBA Rhythm.  What is the overall consensus on this ball?  I was a hammer head years ago, and then got away from it when the Jigsaw series came out.  My honor scores have decreased since (probably not coincidentally).  I want to get a couple balls for next season and am considering the Rhythm.  Even though I throw mainly storm now, I still keep an original blue vibe (started a scratch tourney with it just this year and shot 803 for the first three games while moving pairs each game) and a cherry vibe in the bag.  I do prefer symmetric cores and polished covers for energy retention.  I'm leaning towards a cobalt vibe for standard house shots and something stronger to get inside and open the lane up when the opportunity presents itself.  I just don't know what that stronger ball should be.   Help me out please.   

If you want a stronger symmetric ball, I would recommend a Arson Hybrid which is stronger overall than the Rhythm (more backend motion). Another great rolling ball is the Ratchet or First Blood, but those are asymmetrical pieces... Either of these will do the trick for what you are looking for in your bag!  Hope this helps...
