I'm going to go ahead and assume that you have a spare ball and/or can flatten out your wrist to throw straight at spares. If you don't, get a spare ball and learn to throw straight!!!
That said..
Equipment:
Don't count out the widow. A ball with plenty of games usually smoothes it's reaction out. There are definitely times that call for a ball like that on the PBA shots.
As for 2 more balls, I'd like to see you with a mid-range solid and a low RG pearl. We have similar stats and these types of balls do very well for me on more demanding shots and almost every company has these 2 in their lineup (i.e.: Copperhead and Smash Zone from Brunswick)
Just remember to drill them somewhat mild. Probably in the 4.5" to 5" pin to pap range for you. Pin down with the solid, up with the pearl as this will give you the most diversity out of your equipment. You also might want to add an entry level ball for the shorter patterns as they dry out.
Just remember, play the lanes the way they want to be played. Don't force anything, make your spares and learn.
