I recently pulled out my Pioneer from retirement, and I am very happy that I did. For me at least, this ball hits like a tank. As of late, this has been the first ball that I take out of the bag, every other ball I have is MoRich. Once I get my tax check, I'm having KOTM drill another Pioneer for me and this one will be for dry lanes. The one I have now is more of a medium type shot. While I haven't thrown a Sahara, I have heard good things about it, but in my opinion you can't go wrong if you get a Pioneer. Plus, if money is tight for you, the Pioneer should be cheaper as well. I believe the Pioneer is weaker then the Sahara, but I'm not really an expert on the technical stuff.
