If you're leaving a lot of corner pins and the lanes are dry outside, I wonder if the surface of the V2 STrong isn't too strong, too dull, too rough for the condition. You make it sound like it's getting to the pocket with nothing onthe ball. If I were you, before buying a new ball, experiment with the surface of your V2. Put a little polish, not a gloss shine, just a slight shine on it. Maybe use a bowling ball polish by hand, not with a spinner. Then bowl; check out the reaction. If needs be, then add a little bit more polish.
Maybe this will help it retain energy a little more, for a little more punch.
