I have one and I don't believe the WMB to be a heavy oil ball. There are stronger, yet very controllable balls for heavier oil. I have had great success with the Big Bully but since you seem to like Brunswick, why not an Ultimate Inferno?
On Edit, I saw you don't want an UI. The Big Bully is an excellent ball, it is much stronger in heavier oil than my WMB.
