I currently have a Columbia Rival and a Storm Thunderstruck both solids.  I don't have a strong pearl.  I was thinking of going with the Complete NV or the Total NV.  According to BTM's ball reviews the Total NV got a length of 14 with a backend of 15.5.  I am looking for something that has similar length. I mostly bowl on THS, Speed is around 15-16 and Revs match speed.  My pap is 5 1/4 over and 1 Up.  If someone can explain the differences between the two and which one might work best with my specs.  A layout would be greatly appreciated as well.  



Thanks

Doug
