text: It's really impossible to recommend a bowling ball without seeing you bowl (for instance, what's your typical ball speed?).  The best answer is to visit your local pro shop, tell them that you throw a back up ball, and that you're not interested in being trained out of it, but you'd like a new ball.  Depending on where you bowl, and how the lanes are oiled, there might be something that the pro shop guy can recommend over the others.\n\nAs for a simple recommendation, any entry level resin ball (The Tornado series from Ebonite; Storm, Brunswick, Columbia  each make their own) will give you a simple hook--not a monster hook.
