Debs, I wouldn't be self concious about taking 3 balls anywhere. It's not bad to have a dry/spare ball, a medium ball, and one for heavy oil. I think where people start getting rediculed is for bringing in a truckload. 6 ball rollers are occasional at most leagues I'm at, and I think anything over that for league is what really stirs the pot. Personally, in 2 of my leagues, I just take 2 because the shot never changes. My third league has a better pattern, and multiple lines can be more easily played (more even reactions, and more oil, and not so much over/under) so I take 4 to that league - but mostly wind up using 2 of those, sometimes 3.
