Very little and no. I have plenty of balls with quality plug work in the track. Several honor scores with each. You asked for a certain reaction. As long as that's what you got, it's your fault for not being specific for avoiding plug work in the track. The shop is probably used to putting plugs in the track to get a certain reaction, and didn't think twice about it. I know a lot of people don't like it, but it really has very little effect on ball reaction.
