If its "med-heavy to heavy" for me:
On the heavy side there is no real angular ball. The "No Mercy" with the Drilling #1 (dependig on your PAP) is the most backendish ball i have ever thrown. The bad with this ball is, it was allmost uncontrolable for me and this ball needs real good maintanence, much more then any other i ever had.
On the med-heavy side you can úse Doom or Toxic. For me this two ball are allmost equal. Toxic skids longer, Doom grabs the lane earlyer. Also you can take off the polish, then the Toxic will read also earlyer with bit loss in the Backend.
Again the Doom is in your first year the best ball to go, very controlable easyer to learn with, better looking and the coverstock can be changed to take tons of oil, just ask your local shop. The best of all is, you can save money, buy yourself a spare ball and pay a part of the Lesson you will need for a good start.
