I have a Vandal and have been killing the lanes with this ball.  I have it drilled to go long and hit hard in the back end.  I bowl in a house with a lot of oil but desert condition from 5 board out to the gutter.  The bowlers with the highest averages, in general, play straight.  The Vandal is the first ball out of my bag and I usually bowl around 250 for the first game.  I will usually throw it up the 6 board.  By the 2nd game this part of the lane dries out and I'm pushed much further left. If I try to stay in my spot the ball gets jumpy.  If I moves left my carry goes down because of the amount of oil.  I was thinking of drilling a second Vandal but drilling it to pick up the lane sooner and to be more controllable to use for the 2nd game.  What do you guys think of this dual angle drilling: 45 x 4.5 x 70.  My speed is about 15mph, with average revs and my average is 225 to 230.

Thanks
