IMO if the BW didn't work for you at all, then I'd bet most high MB balls won't either. Or at the least it HAS to be drill for you perfect. Saying that, the best heavy/med oil ball would be the Anger.
I do think some folks see it as a "tamer" ball because it's in the Raw Line and not 'higher' in the line-ups, but remember, Hammer makes the line and not just a "performance" line as does Storm or some others.
The Anger is a strong ball, so talk to your driller and tell him/her what you want and expect or you won't be happy with it, either.
