Correction to the ball description - the RG Diff is a strong .053, not .043.

I bought this ball new and I still carry it in my bag - it is the first ball out - after ten years of use it still hooks the house. It has a very, very predictable consistent reaction the entire way to the pin deck.

I agree with dizzyfugu that the cover stock is basically PK18 with a light load of particles - and as always has been true of PK18 cover stock, it is virtually indestructible.

I use this ball as my benchmark to see what ball I will start the game with - except when the lanes are already toast, I will give the Fuze Eliminator a try - unless you run out of lane it is a very versatile bowl as you can get very deep inside with it on medium dry and still carry. In a total flood you may need to get your go-to oiler.

You can think of this ball as a step up from the Karma solid.

As I have gotten older I have become more cautious so I don't play the "no guts no glory line" much - if the ball has to hang over the channel to stay in the pocket, this one goes back in the bag:)
