well first off i should csay that im a sophomore in high school bowling varsity. im left handed with medium ball speed and rev rate and my home shot is a 40 foot house shot and most tourneys a heavier 40ft house shot. i have a Brunswick Ultre Zone (2000 grit) a Track Rising (2000 grit) and a cell pearl (1500 grit polished) inmy bag right now. i bought ($80) the origional cell off of a friend who had it for a week and didnt like it because it was too strong. my question is should i keep the origional cell and get it drilled and if so how should i get it drilled (pin up, pin down, richo) or should i sell it and buy a different ball if so then what? i like the demension and the way it transitions from the on the back end, but if i sell the cell should i get that or a different ball?
