There are numerous things that can make a ball become a blem, but performance is never one of them. Pretty much all cosmetic things that make a ball not acceptable as a first.
If you have a chance to pick one up at a good price you won't be dissappointed in the reaction, unless, like with any ball, you attempt to use it on the wrong conditions.
