I drilled the Theory using a 4 1/2", 75 degree pin/pap layout, MB 4 1/2" from pap, pin below my ringer finger, small rev leverage hole 2 1/2" below my pap on VAL.
On a PBA experience league Shark pattern (44'), the Theory revved up nicely in the mid-lane and had a strong, controlled move off the break point, with strong roll through the pins. On a PBA experience league Scorpion (41') pattern, the Theory showed the same characteristics. On a 39' house shot, I was able to move in and play off the wet/dry with good results.
The new Triliptic Core, Insight Solid coverstock, and 2000 abralon box finsih, provide a combination of strong roll, good mid lane read, and energy retention. If your Cells are ready for replacement, try a new Theory.
