I have a time zone and I love it . Mine is drilled strong . Mb near thumb , this ball hooks . I bowl on synthetic , I am a high track . I have thrown my time zone when the heads have dried up , standing on 25 swinging out to 10 and coming back hard . Take my advise and get the ball and play with it . If it doesn't react the way you want , take it back to your driller and make some adjustment to the ball . My 2 cents worth .
