28" is a good for eastern KY. Any wider and you will be tagging trees. After you ride with them for a while that's all you will have. Pro tapers woods low for me.
28.5" just to be different. Seriously you need your bars cut down in SW Pa just like others have mentioned. Some bars it's tough to fit everything on when cut down. I've used mini bars in the past because they often have longer flats for room for controls once cut down.
30" here in east tn. I like the extra room on the bar for controls. With the twisted engineering bars, the guards dont add to width. So, 30" bars =30" width overall.
