That's why I was surprised/disappointed. I already have several "light oil" balls and most of them force you too far left, but then don't have the goods to come back with enough authority. I really wanted something I could play straighter closer to the friction.
Yes, the Strike King is polished like you'd expect OOB. The Wicked Siege was extracted 2-3 weeks ago and hasn't seen a lot of action since. I've never done anything to the Yeti. I just had the (new) pro shop re-do the thumb. I didn't throw it much since I got it (50 games max) because it seemed very condition specific (I've only bowled sport shots the last 3-4 years), but part of that may have been that I was never very happy with the thumb - I'd throw it OK during a practice session, but never really trusted it when league would start. I'll throw both Sunday on a fresh Nationals pattern - hopefully that will clear things up.
