I'd say the SR2.  Use it to start and it will tell you when it is time to use the C51 or Recon, as the SR2 is a fantastic benchmark ball.  The QZ2 is a great choice as well, but doesn't quite have that magical read of the SR2.

Thanks for the input guys, my biggest question is I bowl in two different houses.  The first house uses lane shield which is now brand new and plays very slick, which is why the Cruel is a pretty obvious choice.  The other house however is a problem, we bowl Tuesday nights and he oils for the Special Olympics league before us in the afternoon and then lets open bowlers bowl on the pairs we use.  It is only a 16 lane house so every week they play different because with the special olympics god love em, but they throw all over the place and combined with open bowlers there is a lot of carry down combined with burnt up front ends.  I was deciding between the SR2 and the QZ2 on which I thought would play better on these conditions because I am a high rev player and have trouble with the more aggressive stuff I use now.  So my question would be go with the SR2 like you say or get the QZ2, or is there an even better option I have not looked into?  Thanks again

Well I decided to go with the QZ2, the price was a little better and I think it will get through the fried heads that I bowl at in the 2nd house.  Thanks for the input and I will post back what I think about the decision.

I'd rather you hate me for everything I am, then have you love me for something that I'm not!!! 5FDP
