It is VERY difficult to hook a conventionally drilled ball. It can be done, but you will always get more lift with a fingertip ball. If its drilled right, you can definitely stay with the same weight ball. It may take awhile to get use to, and you may need to make small span/pitch adjustments until its comfortable, but ultimately fingertip allows for more comfort, lift, and control.
