Gotta go with the Triple X Factor Xtreme. This is still my benchmark ball, and also does a great job on a broken down pair when pearlized stuff is just diving at the headpin, it gets through the heads, and it smooths out the reaction downlane with enough energy to go through the pindeck.
Close second would by my pearlized teal and purple tropical storm. I have bowled both of my 800's using this ball, one on fresh, one on a second shift and this ball is amazing, especially at the price point.
