I have a Big Rig and a Vibe being deliverd today and i can not make up my mind how to have them drilled. I bowl on a med to med/heavy oil on syn.lanes,i am a senior bowler who strokes the ball and throw around 15mph.Let me add that by the start of the third game no more med oil or light oil so i hope my Vibe will work for me during the third game. Also my PAP is 4 1/4 ovef and1/2 up and i am right handed. Thanks for any help.
