AGREED. I have seen several different folks roll them, and no matter how they are drilled, they all seem to straighten out right before the pins. All you have to do is get lined up.
If you want a Hammer for dry lanes, get either an original black Hammer or one of the original pearls (blue or red).
Don't get me wrong, the Sling is a great ball (I shot 815 with one this season), but like any other ball, you have to find the right condition. Same thing with the Pure Hammer (shot 300 with that one).
