You probably don't need anything higher in price than a Blade from the sounds of it.
What type of lane do you bowl on?
Oily - Saw Blade, Sharp Blade
Medium - Blade Reactive, Switch Blade
Light - Sling Blade
You may want to wait until the end of the summer to get a new ball as Hammer has new additions coming out in June and July.

Lake LeBoeuf Lanes is where real men go to bowl.
