Check out Brunswick Power Groove,Dynothane Vendetta or Ebonite's Prime Time line of balls.These are all mid to low price range balls with proven cover stocks.A general rule of thumb for these covers is Pearl-skid snap,Reactive-arc and particle-early roll hook.All three lines have at least one ball in each catagory.The cores are basic and time proven.At this point in your game exotic drills,covers and cores won't help your game enough to justify the expense.

The Double Helix is a Urethane ball with a reactive center stripe.The idea was the control of Urethane with the hit of reactive when it flipped to the reactive stripe.If your like 90% of the bowlers out there the ball will roll mostly in the urethane area and VERY little of the reactive area comes into play.I don't think you have truly thrown a reactive ball yet.

If I were to recommend one ball to give you the added hook of reactive plus control it would be the Power Groove Pearl.The cover is PowerKoil 17.This is a durable controllable cover.The weight pucks in the core will allow your driller a little more creativity in drill selection.

Dez,
A reactive ball will be a change in your game not only on first ball but with spare shooting.I use a Power Groove for tournament and Sport Shot conditions.I paid $90 for my last one $60 shipped on EBay and $30 for drill.If you can swing I would buy it ASAP and use your summer league to get familiar with it.

Urethane is an excellent control ball and will help you fine tune your game skills.There is nothing wrong with continuing to use the Helix or Scout even after your new purchase if lane conditions dictate.
