I am the one weirdo here but I really liked the Attitude Shift. I had mine cleaned regularly and even had it de-oiled a couple of times and this ball still rolled amazing for me. I could shine it by pad, lane shine it, or scuff it and have a ball that would get good length and good hit.
For me I think it is the core as I liked the Shift, Gravity Shift, Virtual Energy, and the original Virtual Gravity. The Nano and Nano Pearl were not my cup of tea as the covers were a lot different in my hands.
