Drrev,

The QZ1's are in their midrange level equipment meant for medium to moderately oiled lanes.  

The person in the video is actually me and the shot was pretty fresh.  They were Brunswick synthetics with about 3 games on the lane before I started the video.  This house generally has a 5-7 board bank area with moderately stripped backends.

In my opinion this ball fits just underneath the GT1.  The box finish of 1000 polished started reading pretty early and gave a similar look and feel to the GT1.  

I'm not sure what your comment about the skill level of the bowler or lanes was referring to but I thought the carry with this ball was pretty good!  It did however have that Urethane look to it as you mentioned.
