With your slow ball speed, I would recommend a high end pearl to help get the ball down the lane. For your high end, you could do something like a Marvel Pearl, Nexus Pearl, 919C. On the lower end, you would want to do something like a Cyclone or Freeze. Keep it simple. Do pin above the fingers and if you do a layout where a weight hole is needed, make sure the weight hole is small as you dont want to help the ball rev too early in the midlane to prevent the ball from hooking too soon or revving up and dying before it gets to the pins.
Any idea what your axis point is?
