I just recently found a ball for $6 at a thrift shop so I picked it up... Then I found one in the closet at my gmas house... Anyways the one I bought is a 16 pounder and the other is a 14 and I've been trying to learn how to hook with the lighter one. I'm usually around a 100 straight line bowling with the heavy one and topped out at 122 the other day. Last night I took the light one out for the first time and got a 117 top while trying to hook but I'm getting more of a vertical axis spin instead of a nice sideways roll... Anyone got tips?
